The paper presents a numerical model to study the transition of brittle materials from cracked solid granular medium under impact loading. addresses competitive crack coalescence in regime and provides insight into onset comminution initial conditions for subsequent flow. Crack statistics obtained flaws using wing growth-based damage have been used discretely elliptical cracks three dimensions....

Biodegradation of chloroform along with a mixture of VOCs (methanol, ethanol, acetone and toluene) commonly found in pharmaceutical emissions using a biotrickling filter (BTF) was evaluated. The performance of the BTF was evaluated for both steady and transient conditions, for different inlet loading rates (ILR), empty bed residence time (EBRT) and inlet chloroform concentrations. Among the VOC...

Previous findings indicated that in-situ chondrocytes die readily following impact loading, but remain essentially unaffected when loaded at the same magnitude but with a slow (non-impact) loading rate. The current study was aimed at identifying the causes for cell death in impact loading by quantifying chondrocyte mechanics when cartilage was compressed nominally by 5% at different loading rat...

This paper is an investigation of low rate loading of the shoulder. The paper first presents a review of the literature on the impact tolerance of the shoulder in high and low rate loading conditions. Currently, there are no injury criteria, nor biofidelic anthropomorphic test dummies for these low rate scenarios. This study investigates dummy loading situations that are known to be non-injurio...
