摘要:A fast algorithm is proposed to predict penetration trajectory in simulation of normal and oblique penetration of a rigid steel projectile into a limestone target. The algorithm is designed based on the idea of isolation between the projectile and the target. Corresponding f...

摘要:The dynamic fracture and fragmentation of notched rings under explosive loading were modeled to investigate the fragment characteristics (average fragment size and fragment size distribution) and their effects on fragmentation performance. An analytical model of the average fragm...

摘要:By analyzing the fragmentation distributions of a cylindrical structure and a specific structure, the necessity of parallel control to the fragments is presented. The shell shape of structures has an influence on the fragment spatial distribution. A new design method for the shel...

摘要:Abstract(#br)The split Hopkinson pressure bars (SHPB) have been widely used to measure the deformation behavior of materials at high strain rates (10 3 ∼ 10 4 s −1 ). In order to obtain accurate material parameters, the influences of some effects such as friction, inertia, p...

摘要:Abstract(#br)This work devotes to the image deconvolution problem that restores clear image from its blurred and noisy measurements with little prior about the blur. A deconvolution method based on sparse and redundant representation theory is developed in this paper. It firstly ...
