Strain field and damage analysis of clamped square plates subjected to explosive loading;

To obtain more precise prediction of dynamic deformation, theoretical analysis and experimental investigations were carried out on the plasticity dynamic response of clamped square plates subject to underwater explosion loading in a water tank.

Plastic limit analysis of clamped circular plate under linear distributed load;

The superiority of using the generalized functions to solve mechanic problems is illustrated by an example of the bending deflection of clamped circular plate under the concentrated force,using the generalized function.

The unified solutions of load-carrying capacities, moment fields and velocity fields for clamped circular plates in plastic limit state are derived with respect to the unified strength theory proposed by Yu.

The applications of the clamped plate into active acoustic structure are also studied.

Frequencies of the simple propping square plate in vibration by using defletion of the static force were determined,and the frequencies formula for the simple propping square plate in vibration for dispersed and consecutive system were obtained.
