The refrigerator door cover deformation or cracking is a major flaw in the BCD268 refrigerator. In this paper we create a simplified model of the refrigerator door. Based on the standard modules of ABAQUS finite element analysis software, this paper analyzed the deformation mechanism of the refrigerator door, and determined the parts of the deformation. Aiming at the deformation and cracking, the numerical simulation of BCD 268 door cover was conducted, and two kinds of different options to strengthen the ribs were proposed, then the two programs were carried out through finite element analysis, and prototypes were fabricated high and low temperature impact test for validation. Optimal structure scheme was verified by contrast. The designed lower-door covers were produced in small scale, and it proved to be consistent with the numerical results of finite element.

In order to obtain a linear explosively formed projectile (LEFP) with a good flying form under large stand-off, the LS-Dyna finite element analysis software and arbitrary Lagrangian - Eulerian (ALE) algorithm were used to simulate the forming process of LEFP with a 30mm charge structure diameter. On the basis of that, the only changed factor was the curvature radius of the liner which was selected as 0.65D, 0.75D, 0.85D, 1.0D and 1.1D for the simulation of LEFP forming progress. The warhead speed-time curves and fracture surfaces of the LEFP are analyzed, with liner radius decreasing, the projectiles become more slender, and instead, the larger radius liner forms flat and wide LEFP. Slender LEFP is conductive to penetration, however the over small radius which cause the reduction of weight and kinetic energy makes fracture easily, oversize radius influence either end of LEFP that warps upward seriously , what means speed grads of both ends differ greatly .The suitable radius ranges from 0.75D to 1.0D.

Non-linear numerical simulation is done on A-type super high pier by using finite element analysis software ANSYS, obtaining the node stress distribution under load in the node area taken in the sequential layer analysis of overall mode. The conclusion is mainly as follows: the change of width and thickness of cross beam exerts slight impact on the maximum stress of the node while the change of cross beam depth impacts the node stress much. From the computation, it can be concluded that proper reduction of cross beam depth is beneficial to the node stress.

Due to the volume expansion of corroded rebar products, the cracking of the concrete cover would occur, and has a serious impact on the durability of the concrete structure. In this paper, a numerical model was established for the simulation of the corrosion of rebar in concrete structures with the aid of finite element analysis software. The distribution of stress in concrete around rebar, that due to the expansion of these corroded rebar products, was obtained. The theory of elasticity method is used to validate the distribution of stress in concrete around rebar. The location of cracks would be predicted by the distribution of stress in concrete around the rebar.
