Abstract

Fatigue testing is a time consuming test method. Fatigue life prediction methodologies based on S-N curve and residual strength require more number of tests per stress/strain level. Also cyclic heating of material like thermoplastics during fatigue restricts use of high testing frequencies. To tackle this challenge, a test set-up is proposed based on wiffle tree concept which offers fatigue testing on 4 specimens simultaneously.

Keywords: fatigue, wiffle tree, thermoplastic composites, hysteresis heating, force ratio
