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.

In a multi-model control(MMC) version,a majority of local models are based on a linear model and their number and accuracy may influence the effectiveness of the multi-model control.

According to the result of the field observation, the design by load equivalent simplification and plotting out representative local models following spatial strut-and-tie theory are obviously practical, recommendations for design on t.

Study and introduction to the applications of local models in tidal flow numerical simulations in coastal and estuarine waters are made through two case calculations.

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.
