The processes of pipe collapse under external pressure have be calculated and simulated by means of the ANSYS FEA. It introduces the destruction theory of the pipe and some formula by API, and analyses the factors such as geometries, pressure, and its properties, which affect the capability of the resistance to the pipe collapse. The relationship between strain and stress of pipe has been descried...
In this paper, nonlinear finite element analysis about the semi-rigid connected steel frame and top and seat angle with double web angles semi-rigid connection are carried out with ANSYS finite element software. The analysis is a complicated nonlinear problem, which includes plastic development of metal material, geometrical nonlinear caused by large deformation of the structure and contact. Results...
According to the fact that the poor construction performance and durability problems are mainly caused by elasticity cushion in ballastless track slab, a new elasticity cushion with fiber reinforced foamed urethane (FFU) is designed that different from cement emulsified asphalt mortar (CAM) CRTS II elasticity cushion and CRTS I elastic cushion. Then the new elasticity cushion in track slab 3D models...
The finite element model of steel structure of bag filter is established and the stress distribution and deformation of steel structure under different load cases are analyzed with finite element analysis software ANSYS. The results show that the model of bag filter which is established with ANSYS and the calculate method are rational, and the analysis result is reliable, they are supply theoretical...
Based on the experimental results of 12 steel fiber reinforced concrete corbels, the numerical simulation by nonlinear finite element method was adopted to analyze their behaviors and to explore the influence of steel fiber volume ratio, the shear span to depth ratio and the strength of concrete on the shear behaviors, crack and deformation of concrete corbels. The results indicate that the shear...
The development of modern transmission design leads to scuffing becoming more serious for transmission gears. The finite element method (FEM) is proposed that can be used as the most economical and effective designing tool for predicting the gears temperature and the distribution, determining whether the tooth scuffing or not, and analyzing the thermal stress and the deformation of gears. The thermal...
Based on a general finite element software named ANSYS/LS-DYAN, using the function of conversion between implicit and explicit, and adopting a research method in which static analysis and dynamic analysis are combined, a research of dynamic response about underground chamber with blasting shock wave in deep environment is carried out by using numerical simulation technology. In the simulation, implicit...
Commercial FEM software codes do not directly support the cure dependency of polymers behavior. In electronics packaging, for example, cure shrinkage of the molding compound is consequently treated as a surplus to thermal contraction and its changes in visco-elastic behavior during curing are usually ignored. This give rise to inaccurate results and may cause difficulties even in recognizing factors...
The mechanical construction and basic principle of the active polishing lap are introduced, the testing method has been exploited, and the displacement quantity of the deformation has been discussed. The finite element model of the lap has been constructed by the ANSYS, and then the simulation results are obtained under the conditions of the control procedure of the lap. Through the comparison study...
