Tutorial 85: Determining the Fatigue Behavior of Composite Tensile Specimen

Tutorial by Armin Yousefi Kanani

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
