winLIFE 3.7

winLIFE by STZ-Verkehr is a Windows-based fatigue and durability analysis tool for predicting the service life of components and welded structures under real-world loading. Designed for engineers in automotive, rail, off-highway, and general mechanical design, it connects test data, simulation, and established guidelines to help you design for durability earlier and validate results efficiently.

Key capabilities:

• Time- and frequency-domain fatigue analysis using S–N and strain-life methods, including rainflow cycle counting and Palmgren–Miner damage accumulation.
• Handling of multiaxial and non-proportional loading with support for common critical-plane and energy-based criteria.
• Evaluation of welded joints and notched components, with support for recognized standards and guidelines (e.g., FKM, IIW).
• Direct use of measured load time histories and power spectral densities, plus tools for signal processing, filtering, and editing.
• Integration with finite element analysis, importing stress/strain results from leading solvers (e.g., ANSYS, Abaqus, Nastran) and common data formats.
• Material data management with S–N curves and mean stress corrections (e.g., Goodman, Gerber, Morrow), along with tools to derive curves from tests.
• Correlation workflows to compare predictions with test results and support design iteration.
• Clear visualization and reporting of damage, hot spots, safety factors, and life estimates.

Benefits:

• Reduce physical testing by focusing on critical cases.
• Improve reliability by identifying durability risks early.
• Shorten development cycles through tighter test–analysis integration.
