Abstract Details

, Master of Sciences, Case Western Reserve University, EMC - Mechanical Engineering.
J-integral can be used to characterize the crack initiation and propagation process and requires a smaller sample dimensions compare to stress intensity factor (SIF) based test. Yet no studies have investigated the J-integral of dental restoration materials. The aim of this study is to measure J-integral value for dental restoration materials with Digital Image Correlation (DIC) method. Three materials (IPS E-MAX, Vita Mark II and Paradigm MZ100) are used to prepare beam samples for three-point bending test. And a finite element model of VM II was built to validate the strain accuracy of DIC. The critical SIF are then calculated from J-integral (KJ ) and compared with the ones calculated from geometry dimensions and load at fracture (KIC). Generally KIChas a higher value than KJ . Yet there is a good consistency between KJ and KIC , thus proving DIC is an effective way to obtain J-integral for dental restoration materials.
