The method of fatigue and durability analysis employed by PLHAE takes Finite Element Analysis to the next level by accurately predicting a structure or components cycles to failure. Instead of simply looking at the stress, strain, and displacement results of FEA, a number of load cases can be combined in to a duty cycle to determine the summation of damage in order to predict B10 or B50 life. This process reduces analysis time and significantly shortens the number of iterations required to meet performance requirements. With this process PLHAE can shorten the product development cycles.
