Abstract Reactive penetrator has stronger damage effects due to the combination of penetration and blasting. In this paper, numerical simulations are carried on by LS-DYNA understand mechanism a new type segmented reactive-core penetrator. The primary core secondary made W/Zr reactive alloy PTFE/Al composite respectively, which coated steel shell. Different from Penetrator with Enhance Lateral ...

In the field of hardware and software verification, many applications require to determine satisfiability of first-order-logic with respect to one or more background theories, also referred to as Satisfiability Modulo Theories (SMT). The majority of these applications relies on bit-precise reasoning as provided by SMT solvers for the quantifier-free theory of fixed-size bit-vectors, often combi...

Ground vibrations caused by blasting are undesirable results in the mining industry and can cause serious damage to the nearby buildings and facilities; therefore, controlling such vibrations has an important role in reducing the environmental damaging effects. Controlling vibration caused by blasting can be achieved once peak particle velocity (PPV) is predicted. In this paper, the values of P...
