Progressive Damage Analysis of Laminated Composites using Continuum Damage Mechanics
In this paper, progressive damage and global failure of composite laminates under quasi-static, monotonic loading are investigated using 3D continuum damage mechanics. For this purpose, a finite element program has been developed using an eight-node 2D layered element including layer-wise plate theory. Damage analysis of a single orthotropic layer under various uniform in-plane and transverse l...
متن کاملSpringback Modeling in L-bending Process Using Continuum Damage Mechanics Concept
Springback is one of the most common and important issues in metal forming area. Due to the fact that springback depends on a variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) on springback was investigated based on the Lemaitre isotropic unified damage law. Swift’s hardening law was employed to describe isotropic hardening behavi...
متن کاملNon-local modeling of epoxy using an atomistically-informed kernel
An integral type non-local continuum model for epoxy, used as the matrix material in aerospace structural composites, is developed from phonon dispersion data. Non-local continuum models can be used to regularize the stress fields at crack tips and molecular defect cores (e.g. disclinations in epoxies) where local (classical) elasticity theories fail to give bounded solutions. Integral type non...

متن کاملDamage Assessment using an Inverse Fracture Mechanics approach
This paper studies the application of an inverse methodology for problem solving in fracture mechanics using the finite element analysis. The method was applied to both detection of subsurface cracks and the study of propagating cracks. The procedure for detection of subsurface cracks uses a first order optimization analysis coupled with a penalty function to solve for the unknown geometric par...
