PFA - Progressive Failure Dynamic Analysis (PFA_PFDA)
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
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
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.
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.
