3-D solid elements were used in consideration with temperature dependent material properties and effects of phase transition. Internal heat generation and amplitude loading were used for simulating welding heat source movement. The process of multi-pass welding was simulated by using an element birth and death technique. 选用三维实体单元,考虑材料物理性能随温度的变化和相变的影响,采用内部热生成和振幅曲线的加载方法模拟焊接热源的移动,运用单元生死技术模拟多道焊过程。
In addition, considering the effect of construction procedure to the stress of truss-arch, we simulated the assemble order by breath and death calculation. After the analysis, we suggested that the launder should be hoisted by the sequence of middle before end. 另外,考虑到施工过程对桁架拱的应力的影响,用死活计算方式模拟槽身的吊装顺序,分析后建议采用先中间后两端的顺序进行吊装。
A successive transformation of the sintering material from the powder to the high-temperature liquid phase and, afterwards, to the continuous solids was simulated by using a "birth and death" element technique of the ANSYS software. 利用生死单元技术,模拟了烧结材料由粉末态转变为高温液态继而转变为连续实体的过程。
CONCLUSIONS: In an in vitro model of simulated ischemia, MSCs reduce cell death. 结论:骨髓基质细胞可以减少缺血海马片细胞死亡;
The thermal stress during spraying is simulated and analyzed by element birth and death method with ANSYS software. 本文运用ANSYS软件,采用死活单元法对离子喷涂的涂层热应力进行了有限元计算,并进行了定性的分析。
Temperature distribution during wheel piling is simulated using the thermal analysis module as well as "element birth and death" and contact features of finite element analysis software ANSYS ( Ver 6.0), which provide the basis for the numerical simulation of temperature distribution during isothermal treatment. 应用有限元分析软件ANSYS6.0的热分析模块以及单元生死和接触功能,成功地模拟了车轮堆垛过程的温度场,为等温过程温度场的模拟奠定了基础。
