Identification of Material Parameters of Unidirectional Composite Model
Original language description
This work focuses on analysis of longfiber unidirectional carbon-epoxy composite using finite element method on a unit cell. A micromechanical model of the unit cell is created in computational system MSC.Marc using orthotropic elastic fibers and isotropic elastoplastic matrix. The plasticity of the matrix is prescribed in the model by a hardening function. Material parameters of the micromodel are identified using gradient optimization method in OptiSlang system. In the optimization, stress-strain relations obtained from the micromodel are compared with the stress-strain relations from a nonlinear macromodel. The macromodel of the composite material was created in author's previous work. Parameters of the macromodel were identified from experimental tensile tests also using optimization with MSC.Marc and OptiSlang.
