Distortion Analysis of Thin-Walled Investment Castings

Undercooling and nodule count in thin walled ductile iron castings

Accuracy of Investment Castings

In the paper the analysis of wax pattern and casting dimensions changes during each stages of investment casting technology process has been presented. Results of wax patterns and castings of test plate free and restrained contractions dimensions changes research carried out in Department of Foundry Engineering at Brno University of Technology have been presented as well. Moreover obtained resu...

Analysis of Thin-Walled Structures Using Torsional-Bending Elements

In this paper a new element for analysis of thin-walled structures is presented, and the effects of secondary shear stresses on longitudinal displacements are examined. Since the Interpolation Functions are based on non-uniform torsional differential equations, the analysis of stiffness matrix is facilitated. Therefore, its ability to produce accurate results with the least number of elements i...
