Our previous constitutive model for fully dense ceramics has been extended to include A1203 (AD999) and Si3N4; there are now parameters for seven materials. New experimental data, such as spall and double-shock wave-profiles for SiC and B4C, have been successfully simulated. Additional experiments are proposed which should help elucidate the remaining problems.

In Korea, an accelerator-driven system (ADS) called HYPER (Hybrid Power Extraction Reactor) is being studied for the transmutation of the radioactive wastes. HYPER is a 1 000 MWth leadbismuth eutectic (LBE)-cooled ADS. In this paper, the neutronic design characteristics of HYPER are described and its transmutation performances are assessed for an equilibrium cycle. The core is loaded with a duc...

Competition overview: Entrants to the Young Stress Analyst (YSA) competition were invited to submit 1000 word summaries of their work. The submissions were reviewed by an expert panel and four finalists were selected and invited to attend the 10 th International Conference on Experimental Mechanics. The YSA 2015 finalists will present their papers in a plenary session on Wednesday 2 nd Septembe...

Gibbs free-energy calculations based on density functional theory have been used to determine the possible source of failure of boron carbide just above the Hugoniot elastic limit (HEL). A range of B4C polytypes is found to be stable at room pressure. The energetic barrier for shock amorphization of boron carbide is by far the lowest for the B12(CCC) polytype, requiring only 6 GPa approximately...

In this study, to evaluate the effect of boron carbide (B4C) addition on wear performance aluminum (Al), Al6061 and 5, 10, 20 vol.% B4C/Al6061 composites were manufactured using stir casting hot rolling processes. B4C particles randomly dispersed during process; then, arranged in direction a process further improve dispersion resistance composites. Furthermore, continuous interfacial layer betw...
