Door Frame

To prevent the wooden door frame of traditional rural houses from being stuck due to diamond deformation under earthquake and improve the seismic capacity of rural houses, an innovative method of reinforcing the angular displacement of the wooden door frame with channel steel and the diagonal brace is proposed. The rationality of the finite element simulation is demonstrated by comparing the results of finite element simulation and quasistatic test based on reinforced and unreinforced wooden door frame specimens. On the basis of the finite element model of wooden door frame, the seismic performance of channel type and diagonal brace thickness of reinforced wooden door frame and the seismic performance of friction coefficient of unreinforced wooden door frame are studied, respectively. The results show that the lateral stiffness and the lateral bearing capacity of the reinforced wooden door frame increase with the increase of channel steel type and the diagonal brace thickness. The height of the channel steel section of the seismic reinforcement structure should be half of the unreinforced structure. With the increase of the friction coefficient, the lateral bearing capacity of the unreinforced wooden frame increases, while the ductility of the unreinforced wooden frame decreases.

Element Simulation

The change of ambient temperature will cause deformation during the machining process of large-scale aerospace monolithic component. Based on finite element simulation, thermally induced deformation of reinforcing plate is studied in such aspects as reinforcement structure, clamping method and temperature change, and contact function in finite element software is used to simulate the unilateral constraint between workpiece and worktable. The results indicate that reinforcing plate will produce warping deformation due to the change of ambient temperature. Different reinforcement structures and clamping methods have important influence on the deformation positions and degrees, and the deformation is proportional to the temperature change.

Seismic performance is basically required in precast shear wall. This study focuses on evaluation and improvement on precast shear wall seismic performance. By carrying out the finite-element simulation on a precast shear wall spatial model with new connector from a practical high-rise precast residential building, which was named as NPGCS and experimentally tested by low-cyclic reversed lateral loads in early studies, the performance results including strengths, stiffness, stress, and concrete damage ratio distributions were obtained, and the reliability of NPGCS spatial model was verified. According to the testing results, the finite-element simulation for the NPGCS spatial model is reliable and relatively accurate, especially for applying contact and beam elements into numerical analysis of precast interfaces and dowel shear actions, respectively. The strengths, stiffness, stress, and concrete damage ratio distributions from the simulation also supported the experimental results and conclusions.

The simulation of Profiled Steel Sheeting-concrete Composite Slabs is based on ABAQUS,the finite element simulation software.The simulation is compared with the test to verify correctness of the finite element simulation method.By changing shear connectors of composite slabs, studies are performed on the influence of shear-bond property ,the behavior of slip between sheeting and concrete,slip distribution along the composite slabs and so on.The results indicate that setting shear connectors ,such as shear reinforcement and studs, can improve ultimate bearing capacity and reduce the slippage between the interface.The studs’ effect is more obvious.Actual engineering should select suitable shear connectors,so that it can meet the strength requirement and be economical.

Warpage Deformation

Composite panels with “I”-shape stiffeners are widely used, but cobonding process induces large warpage deformation after demoulding. Finite element simulation was used in this paper to analyze the effects of some representative processing parameters on the process-induced deformation. The results show that the deformation increases with the consolidation pressure, the CTE of mould and the friction coefficient. The deformation is more sensitive to the consolidation pressure and the friction coefficient for a shorter part, while it is more sensitive to the CTE of mould for a longer part.

Az80 Magnesium Alloy

Finite element simulation of the effects of mould angle and friction condition on the equal channel angular pressing (ECAP) for AZ80 magnesium alloy were investigated by using DEFORM-3D program. The results show that the curve of load-displacement was divided into several stages including rapid increasing stage, load fluctuation, rapid increasing stage, steady stage and rapid drop stage. Firstly, when the angle decreased from 150°to 90°, the maximum load increased, and the same as energy consuming. In addition, the average effective strain increased with the decreasing of mould angle after single extrusion, while the degree of effective strain uniformity of the sample decreased and keep greater strain grads between inner and surface part. Secondly, the work load ascended with the increasing of the friction coefficient from 0 to 0.3, and one part of load overcome the friction and the other part is used for deformation of the sample. With the increment of friction coefficient, the average effective strain keeps steady value, while the degree of effective strain uniformity of the sample decreased. As mentioned above, large angle mould and low coefficient of friction should be adopted during ECAP deformation for AZ80 magnesium alloy.
