LSDYNA CONNECTIONS — DEMAND RATIO PER SPOTWELD / CONTACT¶
Composes Time Analysis Segments output for swforc / rcforc / nodfor / deforc and computes peak Demand Ratio = peak_force / ultimate_force per connection. Pass / Warn / Fail status against the configured ultimate thresholds. Powers the Root Cause Analyzer’s connections-tool.
