Abstract

In this study, the fundamental steps required for the mechanical analysis of bolted laminated composite structures were revealed. Advanced methods were developed in Fortran and Python to implement nonlinearity to the composite material model using MARC/MENTAT finite element software. Friction and damage parameters for HTA/6376 CFRP material are verified using experimental data sources in the literature. The critical Cockroft-Latham ductile damage parameter of AISI 304L sheet material with its anisotropic properties, which is required for the design of plastically deformable metal components in the composite joint, is computed. Good agreement was obtained between the friction and progressive damage of CFRP composite, ductile damage of AISI 304L, and the external experimental references.
