Crack propagation tests of lead-free solder were conducted using center-notched plates under cyclic tension-compression of three waveforms : pp waveform having fast loading and unloading rates, cp-h waveform having a hold time under tension, and cc-h

In this work, we examined the validity of four methods for measuring the mode I fracture toughness of wood; double cantilever beam (DCB), compact tension (CT), single edge notched tension (SENT), and single edge notched bending (SENB) tests, which ha

This paper presents experimental investigations on particular failure patterns of foundation piles found in Hyogo-ken Nambu earthquake that were probably induced by seismic up-down vibrations. Impact tests on cylindrical mortar specimens were conduct

Influence of accumulative passing tonnage on fatigue crack growth in rail steels was investigated. The fatigue crack growth was measured using compact tension specimens cut from three kinds of rails with accumulative passing tonnage of 100MGT, 200MGT

A stretched zone is formed as a result of blunting and stretching at the tip of the crack during the fracture process. Consequently, the fracture surface becomes fine and smooth. Paying attention to this characteristic, the authors proposed a new met

Impact tension was applied to a PMMA (polymethylmethacrylate) strip specimen with a notch. An inclined notch was introduced by milling specimens before the experiments. The fracture strains enf and esf were measured near the notch root and at the smo

There are two major fracture criteria for notched C/C (carbon/carbon) composite materials. One is that the fracture strength is determined by the fracture toughness criterion, and the other is that it is simply decided by the net section stress failu
