Progressive Damage Analysis of Open Hole Compression Specimens Containing Complex 3D Textile Architectures Using Discrete Damage Modeling and Independent Mesh Method
Abstract
Discrete Damage Modeling (DDM) and Independent Mesh Method (IMM) are applied to progressive damage analysis in angle-interlock woven 3D textile composites with open hole loaded in uniaxial compression. The predictions were made by considering, geometrically nonlinear formulation, thermal residual stresses and compression-shear interaction in the tows in the framework of LaRC04 failure criterion. The effects of each of these consideration as well as their combinations was evaluated and concluded that while each separately has only an incremental effect it is their combined effect that resulted in accurate prediction of the warp direction open hole compression strength in angle-interlock woven 3D textile.
