23rd May, 2006



Summary

A part "mypart" was analysed using the Concept Analyst software (version 1.8). The geometry and loading are presented in figure 1. The maximum von Mises stress in the model is 980.15 MPa.

Figure 1. Geometry and loading of mypart

The background grid size in figure 1 is 5 mm, so that the overall dimensions of the part are 80 mm horizontally by 80 mm vertically. The loads are as follows, referring to the lines indicated by the numbers in circles in figure 1:

1: Bearing force of 1000.00 N

Distributed loads applied as tractions perpendicular to the edge geometry are simple uniformly distributed loads. Tractions tangential to the edge geometry apply a shear stress of the specified value. For tractions in other orientations, consult the Concept Analyst documentation for interpretation.

Rollers boundary conditions prescribe zero displacement in the direction perpendicular to the line on which they are applied.

The Concept Analyst model was given a file name C:\models\report file.mdl.

1. Introduction

The part "mypart" was modelled as a two-dimensional problem in plane stress. Aluminium was selected as the material, having properties:

Young's modulus : 70 GPa
Poisson's ratio : 0.33
Yield stress : undefined
A linear elastic assumption is made.



2. Deformed shape

Figure 2 shows the deformed and undeformed shape for the part. The undeformed shape is shown in the thicker, blue line, while the deformed shape is shown in the thinner, red line. The deformation has been exaggerated for clarity.

3. Shear stress results

Figure 3 shows a contour plot of the in-plane xy-shear stresses in the part. The peak value of shear stress occurs at the point marked with a circle in figure 3 and takes the value 58.45 MPa.

5. Displacement results - x-direction

Figure 5 shows a contour plot of the displacement in the part in the x-direction. The peak value of this displacement component occurs at the point marked with a circle in figure 5 and takes the value 0.2315 mm.
