Visualization of stress distribution in a solid part

Abstract

The direct presentation of three-dimensional arrays is one of the basic visualization problems. Using cross-sections or iso-surfaces, one can not get a full presentation of a structure and peculiar properties of a solution or process obtained. GDT Software Group has developed a semitransparent voxel technique of visualization, which allows solving the problem. Spatial stress distribution in a solid part is one of the striking examples of visualization. The figures show the spatial stress distribution inside a solid part with two elliptic through holes. Figure 1 shows the problem formulation. The one butt-end of the solid part is fixed, and the opposite one is complexly exposed. Figure 2 shows the visualization result of stress distribution inside the solid part, which was realized by an MSC.Nastran solver of MSC.Software Corporation and a ScientificVR ® package of GDT Software Group provided the visualization. The stress distribution through the solid part exposed is visualized well and presented using the semitransparent voxel technique in iso-surface realization. Fig. 1. Problem formulation.Fig. 2.
