An approach based on the superposition of normal finite element on singular terms for the calculation of stress intensity factors is proposed and the work done by prof. 本文探讨了用在奇异项上叠加普通有限元的方法,来计算应力强度因子的问题。
This microelement method enables to fully reflect the functionally graded properties of the materials, and the computational elements are equal to the normal finite elements. 这种细观元法既能充分反映材料功能梯度变化特性;而其计算单元又和常规有限元一样,是一种针对功能梯度结构分析的有效数值方法。
Methods Part of elements under the posterior articulation were removed from a normal finite element model of calcaneus and talus to simulate malformation of compression of the posterior facet after fracture of calcaneus. 方法在跟骨有限元模型上切割部分后关节面,模拟跟骨骨折后的后关节面压缩畸形。
In addition, the paper has also analyzed the performance of stress and deformation of the culvert under load shedding and normal circumstances through finite element method with MARC program, all these can afford the reference to designer for the future. 此外还结合MARC有限元仿真计算对涵洞在减荷与未减荷时的受力与变形性状进行了研究,为今后的设计应用提供了参照依据。
The authors propose an algorithm for computing multiplication tables of optimal normal bases over finite fields, which is better than those corresponding results of Sun. 本文给出了有限域上最优正规基乘法表的一个计算方法,改进了孙琦的相应结果。
