Calculation analysis of torsion and local deformation of plane irregular house structure arrangement (revision);

In order to predict the deformation of the stiffened plates under blast loads,the deformation was divided into the whole deformation and the local deformation.

The influence of performance parameters on the local deformation of the isolated irregular buildings are calculated and analysed by spectral response method and time-hist.

The deformation localization theory of cutting of coal and rock;

Experimental research on deformation localization of mud-sand stone in quasi-plane strain state;

Experimental study on the deformation localization of rock-soil material;

Bifurcation analysis of materials and numerical simulation of strain localization phenomena can provide a new method for analysis of borehole failure,and for its forecasting or control.

It is well known that due to the strain softening behavior, the strain localization along with shear band formation will occur in the dense sand subjected to shearing under drained condition.

Elastoplastic models can’t simulate strain localization due to ductile damage evolution.

Simulation of triaxial compression and localization of deformation;

Experimental studies on localization and bifurcation behaviors of a marble under triaxial compression;

According to the test results of localization and shear bands formation under the consolidated undrained plane strain compression tests on soft clay in Shanghai,it was found that the deviator stress of shear band beginning to form was very close to its yield point in clay soils.

Based on direct shear tests,the development of localization during the failure of rock specimens is studied.
