Multiscale Model for Progressive Damage and Failure of Laminated Composites Using an Explicit Finite Element Method
نویسندگان
چکیده
Initial development of a multiscale progressive damage and failure analysis tool for laminated composite structures is presented. The method models microdamage at the lamina level with the thermodynamically based Schapery Theory. Transverse cracking and ber breakage, considered failure mechanisms in this work, are modeled with failure criteria evaluate at the micro-constituent level using the Generalized Method of Cells. This model is implemented using ABAQUS/Explicit nite element software and MAC/GMC Suite of Micromechanics Codes. Load versus displacement and local strain gage results for two center-notched laminates are compared against results using ABAQUS/Standard and experimental data. Furthermore, damage and failure paths are compared to C-scans and photographs of failed specimens.

A finite element model based on the layerwise theory is developed for the analysis of transverse cracking in cross-ply laminated beams. The numerical model is developed using the layerwise theory of Reddy, and the von Kármán type nonlinear strain field is adopted to accommodate the moderately large rotations of the beam. The finite element beam model is verified by comparing the present numeric...

متن کاملInvestigation of Important Parameters in Residual Stress Determination in Isotropic Plates and Laminated Composites by Slitting Method
In the slitting method, a small width slit is created incrementally through the thickness of the stressed specimen and the released strains in each increment are recorded by a strain gauge. Compliance coefficients relate the measured strains to the residual stresses. This paper investigates the important parameters influencing the calculation of compliance coefficients for isotropic plates and ...
