PFA - Progressive Failure Dynamic Analysis (PFA_PFDA)

View Product Datasheet (PDF)

Product Highlights:

         Performs progressive failure analysis of composite structures using an explicit transient dynamic algorithm, integrating GENOA with the LS-DYNA software. Complicated behavior of composite structures, which include large deformation and extensive material degradation, can be accurately predicted with this simulation module.

         Effective simulation of complete low or high speed impact events, including damage initiation, damage propagation and final collapse of a composite structure.

         Damage in composite laminates at each time interval is simulated at micro level using advanced micro-mechanics. A time marching algorithm progressively updates the degraded damaged properties until the collapse of a structure.

         Tracking material degradation at the fiber/matrix level enables accurate simulation of the global response of a composite structure.

         Multiple element types, including Belytschko-Tsai shell, Hughes-Liu shell, Belytschko-Leviathan shell, Belytschko-Wong-Chiang shell and solid elements, are implemented in GENOA-PFDA.

Applications/Benefits:

         Low and high speed impact analysis.

         Automobile crashworthiness simulation.

         Simulation of complicated nonlinear quasi-static response of advanced composite structures which undergo large material deformations and structural displacements taking into consideration contact boundary conditions.
