Under the full load status stress and displacement of every finite element node of geaxbox and its position counterforce were studied.

PCG methods for solving finite element equations by nodal elements and edge elements are given respe.

A new type of short anchor frame beam was applied to protect the unstable red sandstone slope ,and three dimensional finite element of jointed rock slopes and surface finite element were adopted to calculate the stress and strain distribution of the slope and the internal force o.

Application of rational finite element method in multi-layered composite plates;

As the rational finite element interpolates with the soultions of elasticity and formulates directly in the physical domain, it has superiority over the isoparametric finite element in clear physical meaning and accuracy.

Taking the calculation of the hanging basket structure of a certain bridge as the research object, this paper introduces the theory of and calculating methods for the structural three-dimensional simulation analysis based on ANSYS finite element theory.

On the basis of the primary concepts of thermal conduction and thermal physical property of concrete material, the causes resulting in temperature stress of the concrete structures are analyzed, a compute model for the temperature stress of concrete structures is set up by using the finite element theory, the principles to check of the structure are also given up.
