查询词典 evolution

The structural evolution properties of transition metal clusters containing from 13 to 60000 atoms are investigated by means of the Gupta potential combined with the steepest descent method. Four typical structural motifs are considered: icosahedron, decahedron, face centered cubic octahedron, and hexagonal close-packed.

By using WRF model, the transformation of KOPPU (a tropical storm in 2003 in Northwestern Pacific Ocean) from tropical storm to extratropical cyclone and untransformation KETSANA that will be classifed as "decayer" is simulated, also, the thermodynamic and dynamic structures are analyzed during koppus evolution.

A meso mechanical analysis has been conducted on a hot-rolling steel of 16MnR toinvestigate the effect of the elongated pre-damage voids on the subsequent damage evolution and fracture process under the maximum normal stresses with various directions. The analysis results show that, when the elongated voids due to the decohesion of the inclusions from base material are loaded subsequently, the local high stress and strain concentration around the voids and their interactions promote the growth of voids.

对热轧钢中的长条形初始损伤孔洞承受不同方向最大正应力时的后续损伤演化和断裂过程的细观有限元力学分析研究表明：热轧钢中的长条形夹杂物与基体剥离后形成的长条形孔洞在后续加载中，其周围产生的局部高应力应变集中及其相互作用，使孔洞长大。
