The concepts of sensitivity of strain energy density of the element and the non-dimensional measure used for identification of the element to be modified were presented, and they were applied in topological optimization of bus ceiling under multiple loading cases.

Meso-mechanical analysis has been conducted with finite element for a hot-rolled steel of 16MnR to investigate the effect of the elongated pre-damage voids on the subsequent damage evolution and fracture process under multidirectional maximum normal stresses.

It analyses the strain and the stress in drawing, the existing questions of drawing technology at present, the critical condition of losing stability, the effect on products' quality and drawing die, and the status of the remaining strain.

In order to determine the optimal shape of interchamber pillars,seven models are established using finite element numerical simulation technique to study the influence of different orebody dip angles and different intersection angles between the normal lines of pillar wall and ore bed on pillar strain and stress.

Effect of strain on the electrical resistance of continuous carbon fiber monofilament;

Analog computation of the deformation of continuously casted bloom in secondary cooling zone;

When the burring process of 12×4J wheel is processed taking the deformation area as the plane stress condition,the deformation characteristics of normal and radius directions are studied,which is influenced by the factors such as height and the inner hole initial radius and the deformation law of circle strain.

It focuses on demonstrating special characteristic of prestress and inside dint of the concrete;At the same time,the stress and deformation to the beam construction is examined.
