fe-safe® DATA SHEET DURABILITY ANALYSIS SOFTWARE FOR FINITE ELEMENT MODELS KEY FEATURES • Calculates fatigue lives at every point on a model, producing contour plots to reveal fatigue lives and crack sites • Determines how much the stresses must be changed in order to achieve a target design life, showing clearly where the component is under strength or where material and weight can be saved • Estimates warranty claim curves based on probabilities of failure • Identifies which parts of a duty cycle are most damaging. In prototype testing this could mean shorter tests with fewer actuators • Manufacturing effects such as residual stresses from a stamped or formed part, or the material variation effects in castings and forgings can be included • Automatic detection of contact using contact fatigue algorithms • No special meshing is required. fe-safe works from a standard free tet mesh. Solid and shell elements can be combined on the same model • Unique calculation of the fatigue life of welded joints using the Verity Structural Stress Method • Unique calculation of composite materials using the physicsbased Multi-Continuum Technology (MCT) methods available in fe-safe/Composites™ • Unique methods for fatigue of elastomers using patented elastomer-specific algorithms in fe-safe/Rubber™ • Unique solution providing strain correlated FEA load calculations using the technology available in fe-safe/True Load™ - turns complex components into multi-channel load cells • New method of fatigue analysis from PSDs of loads. Combines a unique method of superimposing multiaxial PSDs with critical plane analysis

• Assemblies of different parts, surface finishes and materials can be analyzed in a single run—fe-safe automatically changes the method of analysis as it moves from one material to another. Contour plots showing the fatigue life at each node, the factor of strength, and probabilities of survival can all be calculated in the same run • fe-safe has many default settings and automatically selects the most appropriate algorithm based on the selected material • Highly efficient coding plus parallel and distributed processing allow fe-safe to analyse large FE models and report results quickly •...

CAPABILITIES OVERVIEW Material database Parallel processing A material database is supplied with fe-safe. Users can add their own material data and create new databases. Material data can be plotted and tabulated. Effects of temperature, strain rate, etc., can be seen graphically. Equivalent specifications allow searching on US, European, Japanese and Chinese standards. Parallel processing functionality is included as standard—no extra licenses are required. Automatic hot-spot formation fe-safe automatically forms fatigue hot-spots based on userdefined or default criteria. Hot-spots can be...
