“…The mathematical-physical model of the macroscopic temperature field required in the simulation process is determined based on the Navier-Stokes equation, and the enthalpy method [9][10] is used to numerically simulate the crystallization process for the alloy. The three-dimensional instantaneous flow and heat transfer process for the alloy melt must conform to Equations ( 1)-(3), i.e., the solidification process of the alloy must take into account the conservation of mass, momentum, and energy.…”

In this work, the CAFE (Cellular Automata Finite Element) model was used to simulate the grain growth of X15CrNiSi20-12 austenitic stainless steel during the investment casting process, and the effects of shell thickness, shell temperature, casting temperature, and cooling rate on the solidification organization were investigated by orthogonal tests. The results show that the cooling method has an important effect on the formation of equiaxed crystals. However, the shell temperature, shell thickness, and casting temperature have a smaller effect on the formation of equiaxed crystals. A more equiaxed fine grain structure can be obtained by using a shell thickness of 7 mm, shell temperature of 1143.15 K, casting temperature of 1913.15 K, and water-cooling conditions. In addition, a decrease in the shell thickness, shell temperature, and casting temperature can lead to an increase in the grain size, while an increase in the cooling rate will lead to smaller grain size and increase the number of equiaxed fine crystals, thus improving the mechanical properties of the material.

The applications of honeycomb structure plate are very important, since its structure have high strength in addition to the low weight. Therefore, these structures are used in the multi-important application, where, more its application is applied to buckling load in addition to other loads. Thus, it was necessary to highlight the buckling behavior of its structure. There, in this research, a suggested analytical solution to evaluate the critical buckling load of honeycomb sandwich plate structure combined from honeycomb part and upper and lower sheet plate parts. Then, the included , by using finite element method, ANSYS program Ver. 15, for various honeycombs core size effect. Therefore, a compare between the results were evaluated analytically and numerically of buckling load are presented to show the agreement between the two techniques were used. Where, the comparison of the analytical and numerical results showed a good agreement of results with a maximum error about (2.24%). Finally, the results showed that the buckling load is modified by increasing the honeycomb core size. There, the upper and lower sheet plate could be used as metal or non-metal materials, [2]. Also, the honeycomb sandwich structure can be made from various materials types as metal, ceramic, composite materials etc. The application of honeycomb structure in engineering leads to supply different loads on the plate. There, one of these loads are the compression load, then, the compression load causes a production of linear elastic deformation of plate structure due to bending behavior of plate. Then, by increasing the compression load on the sandwich plate structure a buckling load is produced on the plate and then a production of bending behavior on it will be shown [3]. results evaluated the mechanical properties of honeycomb part by analytical investigation and buckling load of sandwich plate structure with various parameters effect by the analytical and numerical investigation. The analytical work included the evaluation of the buckling load of a simply supported plate by driving the general equation of buckling the orthotropic plate with buckling load in an x-direction. Also, the results of simply supported honeycombs plate structure were evaluated by the numerical investigationMany studies were presented on the honeycomb sandwich such as mechanical properties, bending behavior, vibration and other behavior of beam or plate honeycomb sandwich with various techniques are

The failure of a knee joint can cause serious health problems and usually leads to the replacement of the joint surgically. The distribution of stresses in the region of the joint shall be computed and analysed via photo-elasticity method and numerically with the use of ANSYS workbench. Numerical stresses will be measured and estimated for ground, air sneakers and ground air sneakers with silicon damped cases and compared with the case of without using damped sneakers. The patient is of age 56 years, weight 85 kg, height 165 cm and leg length of 98 cm. The contours of the distributed stresses via the use of both the numerical and photo-elasticity methods showed that the sneakers with ground, air with silicon damping had minimum stress values (34.71 F& 43,99) MPa for the numerical and photo-elasticity methods respectively. Also, both methods predicted that damped sneakers were safe to use while the maximum safety factor was recorded when using ground, air sneakers with a value of 30. 98 and 30.58 for femoral component, while for tibia component with a value of 17.61 and 18.27, while for articulating surface with a value of 8.63 and 15.94for numerical and photo-elasticity methods respectively.
