TL;DR: It is found that both the node-splitting and overlapping-mesh techniques can be applied to successfully capture the discontinuous displacement field of a propagating crack and the crack-path optimization is capable of locating the crack path with sub-pixel accuracy, reducing correlation residuals and thus increasing the robustness of the DIC analysis.

TL;DR: In this article, the influence of stand-off distance on the dynamic response of thin ductile plates subjected to airblast loading was investigated, and the results showed that the maximum response is driven by the positive impulse from the airblast, as it occurred after the positive duration of the pressure pulse.

TL;DR: In this paper, the fracture characteristics of a cold-rolled, low-strength, high-hardening steel sheet (Docol 600DL) under quasi-static loading conditions are established using five different test set-ups.

TL;DR: In this paper, the authors evaluated the performance of a new shock tube facility used to produce blast loading in controlled laboratory environments and found that the properties of the shock wave proved to be a function of driver length and driver pressure, and the positive phase of the measured pressure time histories was similar to those generated from actual far-field explosive detonations.

TL;DR: In this article, the fracture behavior of a cast AlSi9MgMn aluminium alloy was investigated using a modified Arcan test set-up, where a high-resolution digital camera was used to record a speckle patterned surface of the material.
