RecurDyn/Durability is a toolkit for fatigue simulation

RecurDyn/Durability is a toolkit that calculates fatigue strength and durability such as fatigue life, fatigue damage, and safety factor from the stress and strain results of a flexible body obtained through MFBD (Multi Flexible Body Dynamics) analysis. It provides the prediction theory for engineering fatigue and about 180 material libraries.

In RecurDyn environment, the dynamic analysis of rigid bodies and flexible bodies and the calculation of fatigue strength can be performed quickly and easily without exchanging data with other software. Both FFlex and RFlex are supported.
