CZone for Abaqus is a new add-on for Abaqus/Explicit that provides a powerful methodology for crush simulation, based on CZone technology from Engenuity Ltd. This tool supports the design of composite components and assemblies in the Automotive and Aerospace industries by incorporating material crush behavior into FEA simulations of composite structures under impact.
CZone technology enables the direct implementation of crush-based element force and failure within designated crush zones, typically positioned at the forward edges of the structure in contact with the impactor.
The behavior of the composite structure beyond the crush zone is simulated using existing Abaqus capabilities to address potential delamination, damage, fracture, and buckling. CZone for Abaqus results guide modifications to optimize the placement, thickness, construction, and geometry of crush structures, enhancing their energy-absorbing capacity.
Supported Platforms
CZone for Abaqus is supported on all systems for which Abaqus/Explicit is supported and works with Abaqus 6.8-2 and up.
Applications
- The degree of material crushing and various modes of composite failure
- The energy absorbed in the crush zone
- The forces produced by material crushing
Applications
- Aerospace Engineering: Used for designing lightweight and strong components in aircraft and spacecraft.
- Automotive Industry: Applied in the development of high-performance parts that reduce vehicle weight and enhance fuel efficiency.
- Marine Engineering: Utilized for constructing hulls and components in boats and ships, focusing on durability and performance.
- Civil Engineering: Employed in designing structures that require high strength-to-weight ratios, such as bridges and high-rise buildings.
- Sports Equipment: Used in the design of high-performance sports gear, including bicycles, skis, and racquets.
- Wind Energy: Important for designing turbine blades that need to withstand extreme conditions while maintaining light weight.
Benefits
- Enhanced crush simulation.
- Targeted design optimization.
- Integration with existing Abaqus tools.
- Direct implementation of failure modes.
- Compatibility with multiple platforms
