By employing large deformation governing equations expressed in the form of finite difference,thedynamical responses of elastic,perfectly plastic cantilever subjected to an oblique impact at its tip are numerically studied.

The results of experimental investigation associated with the oblique high velocity impact of cylindrical projectiles onto aluminum Whipple shielding scheme are presented and analyzed in this paper.

Numerical study on the impact absorption behavior of compound tubes;

Failure behavior of laminated composite cylindrical shells under axial impact loading;

Experiment Study on the Impacting Hurt Between RBC and Solid Surface;

The elastic-plastic dynamic response of elastic foundation in collision;

A spring between the ship and the structure is taken into account,and the moment separation between the moving ship and the structure during the collision can be predicted.

The overall thought of application of the passive safety protection technology in the design and research of the crashworthiness of urban railcar sets is discussed.

According to the structural specialties of passenger car designed for Iran,the design of the energy-absorbing structure was done in this paper,and the technical problems existing in structuctural design were solved,finally a numerical simulation of crashing was also done using the ANSYS/LS-DYNA3D.

Feng s novels reveal modern people s confused and impetuous mentality in the crash and mingling of traditional culture and modern civilization.

Based on the result of investigation and inspectiong for the bumped wharf,and a lot of message about the bumped wharf have been known.

The bumping tests of H-shaped posts and O-shaped posts with W-beam guard-rail for the expressway guard-rail were carried out, the test results were analyzed and compared with the traditional guard-rails in this paper.
