Abstract
The fatigue life estimation of a product having elasto-plastic behavior
which results from preloading and holding of catch and strike has been
studied through strain measurements and numerical calculations. The
distributions of the plastic zones have been analyzed using finite
element method and the loading history has been obtained through strain
gage measurements of the different strike thickness and separation. The
experimental measurements have been used as input load in the numerical
analysis. It has been found that the plastic deformation region can be
redesigned to reduce the stress concentrations by adjusting the tension
limits and initial catch-strike separation for predetermined product
service life. (C) 2012 Elsevier Ltd. All rights reserved.... Show more Show less
