Material Efficiency in Industry:
Material optimization is key to the industry’s current transformation. Manufacturers focus on lightweight, durable components for cost-efficient production, reduced warranties, lower recall costs, and faster timelines. While advanced finite element analysis is essential for stress calculations, many companies still use manual stress point selection for fatigue analysis, a time-consuming and error-prone method that risks missing critical failure points.
FEA Fatigue Analysis:
fe-safe is a leading fatigue analysis software for finite element models, setting the industry standard since the early 1990s. Widely recognized for durability analysis, it integrates seamlessly with major FEA suites like Abaqus, ANSYS, and Nastran, making it ideal for the most demanding industry applications.
Fatigue Analysis Methods:
fe-safe was the first commercial fatigue analysis software to focus on modern multiaxial strain-based methods and continues to set the standard. It offers unified access to all portfolio solutions through a single token pool in its Extended Packaging. Known for its accuracy, speed, and ease of use, Fe-safe integrates seamlessly into any design process, making it ideal for even the most complex fatigue analyses and helping to create durable products.
Fatigue Analysis Software provides:
- fe-safe: Delivers accurate and reliable multiaxial fatigue analysis, regardless of model or loading complexity.
- fe-safe/Rubber: Pioneering technology for the fatigue analysis of elastomers.
- Verity Module: Features the patented Verity™ Structural Stress Method for analyzing seam, structural, and spot-welded joints.
- Smooth integration: Enables seamless workflow between SIMULIA products like Abaqus, Isight, and Tosca.
