  1. The elastic constants of bcc li, na and fcc al crystals have been evaluated as functions of pressure and temperature by using a new model together with ab initio electronic structure and total - energy calculations. in the model it is considered that the elastic constants of crystals at a given temperature and pressure can be calculated using a conventional density functional method but modified by a new set lattice constants due to the isobaric volumetric thermal expansion when temperature rise from absolute zero to the given one

    本文對高壓及有限溫度立方金屬彈性常數的計算方法進行了研究,建立了一種考慮溫度效應的物理模型,基於這個模型和從頭算方法,對典型的立方晶系金屬li 、 na 、 al在高壓及有限溫度(熔點以下溫度)彈性常數進行了計算,取得了與已有實驗結果較好相符的計算結果。
  2. Lerr is obtained through tracing the variety of elastic energy density of each element and recording the maximal fluctuation when brittle failure happens during numerical calculation

    該指標的實現是通過在數值計算中追蹤每個單元彈性能量密度變化的全過程,記錄單元發生脆性破壞前後的彈性能密度差值,得到單位體積巖體突然釋放的彈性能量。
