How composite impact simulation links a drop-tower hit to ply damage, delamination and compression after impact: explicit models, cohesive-zone mesh rules, erosion and mass-scaling pitfalls, rate and heat effects, crush structures and surrogates.
How composite delamination simulation works for unidirectional laminates: ply-level damage against cohesive zones and XFEM, mixed-mode delamination, mesh and cohesive-length rules, size and ply-thickness effects, coupon calibration, design allowables and surrogates.
How cold forging simulation predicts die stress, tool fracture, workpiece cracking and dimensional error across forming stages, and how a calibrated die-set workflow keeps those answers repeatable.
A practical guide to modelling composites at the micro, meso and macro scale: what each level predicts well, what it costs, and how to combine them in one validated workflow.
Have a model that will not converge?
Send the geometry, the physics and the decision it has to support. We answer with an approach, not a sales call.
