Abstract
A method for analyzing fatigue life of an elastomeric component includes a step of conducting a finite element analysis to obtain a base state. A plurality of case vectors are then selected to represent a space of possible loading states that occur within a time-varying load data signal based on measurement of the elastomeric component or vehicle dynamics. For at least a portion of the case vectors, a finite element analysis is conducted at a plurality of discrete gridpoints along the case vectors starting at the base state and tracking the case vector. Using an interpolation engine, desired local solution variables for a current state may be interpolated from the finite element analysis at the plurality of discrete gridpoints. A damage calculation may then be calculated based on the desired local solution variables for the current state.
