The Relationship

Synchronized hydraulic bulging forming technology on three-layer-metal tubes was studied. The possibility of three-layer-metal tubes formed by hydraulic bulging method was discussed and proved by elastic-plastic theory. The calculation formulas about the bulging pressure, the residual contact stress and the relationship between them were derived and the main process parameters were analyzed. Finite element analysis was carried out on bulging forming process using MSC. Marc. Practical bulging forming experiments were conducted and well compounded three-layer-metal tubes with tight interfaces were obtained. Through the comparison of the results of theoretical analysis, numerical simulation and practical experiments, proper parameters for the bulging process were obtained and the theoretical analysis was verified and proved.

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.

Superplastic blow forming with diffusion bonded sheet is an effective forming technology for the production of multi-cell structures which should have light weight and high stiffness for aerospace purpose. In the current study, finite element analysis on superplastic blow forming process has been carried out in order to improve the forming process when manufacturing axi-symmetric multi-cell structures using diffusion bonded Ti-6Al-4V multi-sheets. The simulation focused on the reduction of forming time and obtaining finally required shape throughout investigating the deformation mode of sheet according to the forming conditions, which are diffusion bonding pattern and die geometry. To reduce forming time, a preforming die was required, and to obtain the final shape the bonding pattern should be also modified within allowable geometrical margin, so that the sheet is easy to deform. Moreover, an intermediate simulation result, which was forming pressure profile, was employed in real forming test to check if the prediction was reasonably on progress. In the future, a study on the thickness ratio between each sheet should be followed to obtain optimum process parameters.

Distribution Of 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.
