| Fracture and fragmentation studies on 80 ml/kg Anvil Points oil shale with plate impact, Hopkinson bar, capacitor discharge, and HE techniques have shown that the dynamic fracture stress, fracture energy, and fragment size depend on the rate of tensile loading. A model coupling fracture, fragmentation, and stress wave propagation and based on the activation and growth of an initial Weibull distribution of fracture-producing flaws has been found effective in describing the observed rate-dependent fracture phenomena from static to high strain-rate impulse Ioading. The fracture model has been incorporated into one- and two-dimensional stress-wave computer codes and is being used to evaluate blasting geometries and stress-pulse tailoring for in situ rubblization of oil shale. |

感謝大俠出手相助,摘要中我不確定第二句的意思:A model coupling fracture, fragmentation, and stress wave propagation and based on the activation and growth of an initial Weibull distribution of fracture-producing flaws has been found effective ...... "the activation and growth of an initial Weibull distribution of fracture-producing flaws "我譯為:模型內(nèi)部存在能誘發(fā)裂隙開展的缺陷,初始滿足威布爾分布,基于這些缺陷的激活和發(fā)展…… |
