Normalized specimen thickness requirements of a compact sandwich test for measuring fracture toughness of bone.
AIM Fracture toughness is one of the properties that assesses bone quality. Compact sandwich (CS) test gives a better choice of bone sample size and therefore suits a wide variety of fracture toughness testing needs and constraints. This study addresses one of the important standardization aspects of CS test for fracture toughness testing of bone. The aim of this study is to establish normalize...

متن کاملFracture toughness of dental composites determined using the short-rod fracture toughness test.
Plane strain fracture toughness (KIC) has been evaluated for a number of commercially-available dental composites. A modified Short-rod Fracture Toughness (SRFT) specimen design has been used, enabling small specimens to be tested conveniently. The effect on KIC of aging in water at 37 degrees C for seven days, one month, and six months has been determined for conventional, microfilled, and hyb...
متن کاملfracture toughness evaluation for brittle polymers under combined tensile-shear loading
fast fracture is one of the major failure modes in brittle polymers. generally, crack growth in these polymers may occur under combined tensile-shear loading. however, the fracture test data reported previously for some dental restorative resins can not be predicted by using the available fracture criteria.in this paper, a modified fracture criterion is used for estimating the fracture load for...
متن کاملEvaluation of Cleavage Fracture Toughness for Steel by Chevron-Notched Specimen
Fracture toughness tests were conducted for an A533B-1 steel by using chevron-notched compact specimens in the temperature range from the lower shelf regime up to the transition temperature in order to assess the R-curve for cleavage fracture. The applicability of these specimens to the simple fracture toughness test without introducing fatigue pre-cracks was examind. The following are the summ...
