Simulation software Czone

designconstruction

Overview
CZone for Abaqus is an add-on for Abaqus/Explicit that implements a validated methodology for crush simulation of laminated composite structures. Based on the CZone technology from Engenuity Ltd., it enables inclusion of material crush behaviour in FEA to support design and validation of energy-absorbing composite components for automotive and aerospace applications.

Core functionality
CZone implements crush-based element force and failure directly in defined crush zones, typically located at forward edges in contact with the impactor. Outside crush zones, the composite structure is modelled with Abaqus native features to capture delamination, damage, fracture and buckling.

Simulation outputs

• Extent of material crushing and other composite failure modes
• Energy absorbed in the crush zone
• Forces generated by material crushing

Design use
Simulation results guide optimisation of placement, thickness, ply construction and geometry of crush structures to maximise energy absorption and inform design decisions.

Supported platforms
CZone for Abaqus runs on systems supported by Abaqus/Explicit and is compatible with Abaqus versions 6.8-2 and later.
