Research of shielded/structural integration B/Pb composites structure and mechanical properties
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 5
Abstract
With B phase and Pb as the main elements and the designed constituents and structure, a setting shielded/structural integration nuclear shielding materials with the neutron and gamma-ray shielding and the mechanical bearing capacity a setting are prepared. Through analysis of the morphology and mechanical tests, the diffusing refinement and control methods of B phase are studied. The ratio, morphology and distribution of the B phase which affect strength and ductility of the shielded/structural integration materials are studied. The ways to enhance strength and ductility of the shielded/structural integration materials are further founded.

重力坝应力的临界能量误差限自适应有限元分析
本文应用自适应有限元法对重力坝应力的能量误差限进行了研究。通过对不同坝高,不同上游、下游坡比等多种形状重力坝坝体的应力分析,得出在重力坝应力分析过程中存在临界能量误差限,该误差限对不同坝体外形会有微小变化。该结果将会有助...
