Composite materials are created by combining two or more layered materials, each with different properties. These materials have become a standard for products that are both light and strong. Composites provide enough flexibility so products with complex shapes, such as boat hulls and surfboards, can be easily manufactured. Engineering layered composites involves complex definitions that include numerous layers, materials, thicknesses and orientations. The engineering challenge is to predict how well the finished product will perform under real-world working conditions. This involves considering stresses and deformations as well as a range of failure criteria. ANSYS Composite PrepPost provides all necessary functionalities for the analysis of layered composite structures.

Random vibration analysis is another spectral method. The purpose of a random vibration analysis is to determine some statistical properties of a structural response, normally the standard deviation (1σ) of a displacement, force, or stress. (1σ) Is used to determine fatigue life of structure. In this tutorial, first we will model tensile specimen in ACP tools. Then we need to find 10 modes of specimen between 0 Hz to 1500 Hz frequencies. After that we need to calculate Sigma RMS, N, occurrence and V0 to calculate life time of specimen. Agenda: Creating Composite Tensile specimen in ACP Importing ACP model into modal analysis Finding Mode Shapes Introduction of random vibration Applying boundary conditions Determining the fatigue behavior of composite tensile specimen

Tensile testing, is also known as tension testing is a fundamental materials science test in which a sample is subjected to a controlled tension until failure. The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under other types of forces. In this tutorial, first we are going to model specimen geometry in CAD software then we will apply composite layers in ACP tools. In the next step, we are going to model two metal parts and then at the end we will combine models into static structural. Meshes can be imported into Mechanical from multiple systems. It is possible to combine composite shell, composite solid, and non-layered shell and solid meshes to perform mixed analysis.

Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal material cost. The geometry of honeycomb structures can vary widely but the common feature of all such structures is an array of hollow cells formed between thin vertical walls. In this tutorial we are going to create sandwich composite plate. First, we will create two composite plates in two different ACP and then we will create honeycomb in mechanical model by using Honeycombcreator extension. Then, we will combine three models into static structural to do stress analysis. At the end we will do eigenvalue simulation.

Debonding is another type of interface/interphase failure, which is often classified as interfiber failure. It is simply attributed to the nature of the bond between fiber and matrix, whether occurring through a zero-thickness interface or an interphase region. Debonding is simply a loss of physica/chemical connection between the reinforcing material and the matrix. This could occur for part of a fiber, whole fibers, or many fibers. Simply we can say Debonding happen when two materials stop adhering to each other and Delamination when a laminated material becomes separated, perhaps induced by poor processing during production, impact in service or some other means.

Composite fracture occurs at three modes, depending on three loading scenarios. Mode I is an opening or tensile mode, mode II fractures consist of a sliding or shear effect and mode III fractures occur due to a tearing or shear loading effect. This report will only be looking at fracture modes of type I and II. In practical occurrences of material fracture caused by cracking, especially in metals, mode I type of fracture is predominantly present.

ACP has a pre- and post-processing mode. In the pre-processing mode, all composite definitions can be created and are mapped to the geometry (FE mesh). These composite definitions are transferred to the FE model and the solver input file. In the post-processing mode, after a completed solution and the import of the result file(s), post-processing results (failure, safety, strains and stresses) can be evaluated and visualized. After a completed solution, the post-processing is used to evaluate the performance of the design and laminate. The post-processing functionality for Solid Models of ACP allows the mapping of ply wise results on to the reference surface of the solid model. This ensures that also failures occurring inside the laminate can be observed and investigated. Failure criteria are used to evaluate the strength of a composite structure. Several failure criteria can be defined, combined and configured in the Definitions object. Failure criteria definitions can be used for failure plots and sampling points. The critical failure mode for an element shown in failure plots and sampling points is the one with the lowest reserve factor.

An Oriented Selection Set is an Element Set with additional information about the element orientations. The orientation direction of an Element Set is responsible for setting the stacking direction of the associated lay-up. The Reference Direction is responsible for setting the 0 direction of the associated layup. These two directions must be defined while other parameters like Selection Rules and Draping are optional. The laminate is modeled by defining different Oriented Selection Sets for the different regions. The modeling plies are then associated with the OSS and their order defines the stacking sequence of the laminate. The OSS feature allows you to define several offset directions for one element: OSS can overlap and can have different orientations. In this tutorial we are going to model T-Beam by defining various oriented selection sets. This beam is made from three main parts which are: Top and middle surface, Bonding and covering layers.

Tutorial 76: Stress Analysis of Composite Pressure Vessel (Solid modeling)

Meshes can be imported into Mechanical from multiple systems. It is possible to combine composite shell, composite solid, and non-layered shell and solid meshes to perform mixed analysis. Mechanical does not allow overlap of node/element number from multiple systems; therefore, the import fails if the meshes from different systems are overlapping in node/element numbers. Meshes from upstream to downstream Mechanical Models are renumbered automatically to avoid any overlap. For every analysis system (mesh), you have the choice between automatic renumbering (default) and manual configuration. If automatic renumbering is disabled, you must ensure that the element/node numbering is unique for each mesh. In this tutorial, first we will model Composite pressure vessel in ACP then we will model metal parts in mechanical model and at the we will combine models in static structural.

Solid model settings control how the solid model is divided into elements in the thickness direction and how drop- and cut-off elements are handled. The level of detail required in the solid model depends on how accurate certain features are to be modeled. This depends on the judgment of the designer. Extrusion guides add more complex possibilities in shaping the model. The cut-off operation is analogous to machining a composite part after curing. In this tutorial we are going to use extrusion guide, cut off element and snap to geometry to create complex geometry.
