The analysis was performed to compare a beam constructed of the Icosahedrons fabricated of Aluminum to a standard Wood beam. The predicted deflections are similar, while the component stresses in the Icosahedron beam aregenerally low. The finite element analyses were performed using Cosmos/M from ...

In this paper we compare the results from a bending cantilever beam experiment with the theoretical values and COMSOL finite element simulation. In the experiment a simple cantilever beam with a hole is loaded at the end. This geometric discontinuity causes a stress concentration around the hole ...
Finite Element Method (FEM) based electro-chemo-mechanical models that solve transport equations in order to calculate stress and strains at micro-structure scale, have also been widely used [204,205]. To understand the effect of a reduction in the electrode–electrolyte surface contact area on ...
Stress Intensity Factor is a parameter which represents the intensification of stresses in the near neighborhood of a crack and it is a function of the applied load, geometry of the structure and the length of the crack. A knowledge of the Stress Intensity Factor permits one to assess the ...
If the beam is subjected to a shear of V = 30 kN, determine the wed's shear stress at A and B. Indicate the shear-stress components on a volume element located at these points. Set w = 200 mm. Show that the neutral axis is located at \bar{y}=0.243...
In recent years, with the rapid development of finite element approaches, studies have introduced the finite element method (FEM) for the calibration of the release coefficient, which simplifies the complexity and difficulty of calibrating it. In the past five years, a great deal of research work...
the 3-D 20-Node isoperimetric element is adopted.The analysis of SIF is carried out for corner crack of four different cracks' position by using the engineering finite element software-ANASYS.The influence of the crack length and the structural parameter of Ⅰ-Beam for SIF are discussed.The ...
A simple but robust 4-node hybrid stress-function (HS-F) membrane element with drilling degrees of freedom is developed based on the principle of minimum complementary energy. Its stress fields are derived from the first seven fundamental analytical solutions of the Airy stress function. The assume...
