CZone for Abaqus
An Abaqus-based application providing advanced crush simulation for energy-absorbing structures made from laminated composites
CZone for Abaqus is a new add-on capability to Abaqus/Explicit that provides access to a state-of-the-art methodology for crush simulation. Based on CZone technology from Engenuity Ltd., and targeted toward the design of composite components and assemblies in the Automotive and Aerospace industries, CZone for Abaqus provides for inclusion of material crush behavior in FEA simulations of composite structures subjected to impact.
CZone technology provides direct implementation of crush-based element force generation and failure in defined “crush zones,” typically located at the forward edges of the structure in direct contact with the impactor. CZone for Abaqus simulations determine the extent of material crushing and other modes of composite failure, the energy absorbed in the crush zone, and the forces generated by material crushing. The behavior of the composite structure outside the crush zone is simulated utilizing existing Abaqus capabilities to account for possible delamination, damage, fracture, and buckling.
With CZone for Abaqus results as a guide, a proposed design can be altered to optimize the placement, thickness, construction, and geometry of crush structures to maximize their energy-absorbing capacity.
