Abstract

A parameter study with use of the finite-element method (FEM) was conducted for the determination of the setting expansion of gypsum-bonded investment. In this study the FEM was applied to the setting expansion within an elastic ring, and the results of FEM analysis were compared with the values measured and the values analytically obtained. The agreement of the results was clarified when the step number for calculation was increased. The present formulae appear to be reasonable for comparison of the value for setting expansion.
