The method of killing activating elements is proposed here to avoid the prestressed loss.

The method of element birth and death was applied to simulate the model of loading welding heat source.

The paper briefly introduces several heat source models in numerical simulation of welding processes,including Gaussian distribution,double-ellipsoid distribution and birth-death element.

The process of multi-pass welding was simulated using a technique of element birth and death.

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.

The paper actualizes the structural initial load using the element birth and death technology,and contrasts the RC beam strengthened with CFRP on the bottom face with the one strengthened with CFRP on the side faces.

Based on "birth and death of element" and "APDL language",a series of 3-D finite element models is established with current software,and subsequently the deformations of concrete filling are analyzed in the case of the arch foots altitude difference separately being 0.

The technique of “birth and death of element” was brought in the finite element model of construction simulation, which simplified the analysis process.

In order to obtain the most superior lightweight locomotive frame structure,based on ESO(evolutionary structural optimization),the ANSYS\'s birth and death of element function redevelopment were applied,the element with relatively low stress or low strain energy density was "killed" by setting a stress threshold,and the topology optimization procedure was established by APDL.
