Sensitivity Analysis of Damage Models for Epoxy Resins

The parameters for damage models are determined viaa reverse engineering approach. The temporal development of the damage is simulated with cyclictension-compression tests and the parameters of themodel are identified by the matching betweenexperiment and simulation. Moreover an analysis of sensitivity for the relation between model parameters and damage evolution is to be examined.In addition a design of experiment (DoE) is accomplished using the programs Ideas AbaqusOptiSLang and Cornerstone. The following are the three operational joints:-Background1. Damage mechanics2. Experimental methods to determine the material-parameters1. Evaluation methods for cyclic fatigue tests2. Software (IDEAS ABAQUS OptiSLang Cornerstone)3. Models and their implementations-Computations1. Selection of the material models2. Planning DoE (Cornerstone)3. Executing DoE (OptiSLang ABAQUS)4. Analyzing DoE (Cornerstone OptiSLang)-Evaluation1. Models Suitability for reverse engineering approach2. Parameter identification strategies improvement3. Formulation of alternative models and/or extensionof the experimental database.
