This tutorial demonstrates the simulation of the forming process for a steel-CFRP-steel composite plate in Abaqus. The steel layers are modeled as 3D shells, and the CFRP core as a 4-layer 3D shell. The die and punch are modeled as analytical rigid bodies. Lightweight multi-material designs like steel-CFRP hybrids are increasingly important in automotive applications to reduce weight, improve fuel efficiency, and lower emissions. Fiber-metal laminates (FML) combine high-strength steel and CFRP layers, offering cost-effective, stiff, and lightweight structures that can be formed using processes like deep drawing. Steel parts use an elastic-plastic material model, while CFRP is modeled with lamina elasticity and Hashin’s damage criterion. The dynamic explicit step with mass scaling simulates the forming process, with surface-to-surface contact defined between tools and plates and perfect contact assumed between layers. Proper boundary conditions and fine mesh ensure accurate results. Outputs include stress, strain, displacement, and damage data.
