Stress And Strain Distribution

Three-dimensional integrated modeling method and the numerical simulation of elastoplastic finite element are adopted in the paper. The mechanical response of the five holes anchorage is analyzed in certain prestressed state. The stress and strain distribution information of the anchor ring, clip and steel strand is obtained respectively, and the structure safety is discussed by investigating on the maximum stress and strain.

Millions in the world suffering diabetes mellitus depends on insulin therapy to control their blood glucose level daily. However, the painful daily injections they need to take could lead to other complications if it is not done correctly. To date, it is suggested by many researchers and medical doctors that the needles should be inserted at any angles of 90º or 45º. Nevertheless, this recommendation has not been supported by clinical or biomechanical evaluation. Hence, this study evaluates the needle insertion for insulin therapy to find the favourable angles in order to reduce injury and pain onto the skin. Finite element analysis was done by  simulating the injection of three-dimensional (3D) needle model into a 3D skin model. The insertions were simulated at two different angles, which are 45ºand 90º with two different lengths of needles; 4 mm and 6 mm. This study concluded the favourable angle for 4 mm needle to be 90º while 6 mm needle was best to be inserted at 45º as these angles exerted the least maximum stress and strain onto the skin.

The 3d model of miter gate has been set up based on skeleton model of Pro/E, and it has been imported into ANSYS Workbench module for static structure analysis and modal analysis. In the process of finite element simulation, the rotational constraints has been imposed on the top and bottom pivot according to the actual operation situation of the miter gate, and obtain the first several order frequencies and corresponding modal vibration mode of the miter gate, which can show the hydrodynamic vibration stress and strain distribution. According to the results of the finite element simulation analysis, the prototype vibration test of the miter gate has been done. The test results show that the vibration amplitude and the stress and strain distribution of each part of the miter gate are corresponding to the vibration test.

Numerical simulations are done for stretch forming of uniaxial geogrid. And influence of different punching radius on the stress and strain of geogrid are studied. It shows that the maximum stress and strain in tensile process appear at the corner of the circle and straight edge. And the biggest stress is decreased with the radius. At the same time, radius increases reduce the deformation along the stretching direction on some extent. Based on this, a new optimization method for geogrid stretch forming is proposed. The shapes and sizes of punching can change the stress and strain distribution in the geogrid, which can reduce the probability of defect in the process of stretch forming.

Stress And Strain Distribution

Crystal plasticity deformation of aluminium plays an important role on the investigation of macro deformation. In this paper, to discuss the effect ot crystal plasticity on the aluminium material behavior, crystal plasticity theory and macro finite element was combined together. The basic theory of crystal plasticity and finite element was introduce and the simulation result of aluminium was given. The stress and strain distribution was discussed and the efficient of the method was shown. It is shown that the orientation of the material and other micro character of the materials all influence the plasticity behavior of the material greatly.

Stress And Strain Distribution

A certain thickness of two, three and four layers of axisymmetric finite element bellows model were built by Abaqus firstly. Then the axial stiffness and stress and strain distribution of multi U-shaped bellows were simulated by finite element analysis. The results showed that in the case of a constant thickness, with the increase of the number of layers of the bellows, the stiffness of the bellows would be significantly reduced, and in the case of large deformation, the overall stiffness of the bellows would change significantly and was divided into elastic stiffness and plastic stiffness.
