a nano/ultra-fine grain al-0.2wt% zr alloy was produced by accumulated roll bonding (arb) processafter 10 cycles. the fraction of high angle grain boundaries increased from 8% to 65.4% during 10passes during arb process. this alloy was subjected to tensile test at different temperatures (523,573and 623 k) and strain rates (0.1 and 0.01 s-1). the optimum condition of temperature and strain rate ...

  Abstract   Many concrete structures may be exposed to high rate dynamic loadings like impacts, explosions, etc. Thus, it is necessary to know the behavior of this material in order to predict the response of the structure. Understanding the response of concrete at high strain rates is a main factor both for a successful design of protective structures and reducing the damage of constructions....
