| 内容記述 | In this report, effects of length to setting and thermal expansions, (they were published by Yamane (1966) and Kozono (1971)) were elucidated by means of the dynamic stress analysis. Results were follows; 1. Setting expansion of the investment is prevented by casting ring and embedded wax pattern. The deformation of the mold is caluculated as the same as the elastic material's deformation, with thier Young's modulus and Poisson's ratio. 2. The thermal expansion (a) of the investment is influenced externaly by the preventions against setting expansion due to casting ring and embedded wax pattern. But it is determined by the following equation, when the investment is heated higher than 300℃. a=a_1+a_2a (f/f-β) -γ a; Thermal expansion modulus of the investment. a_1; Sum of thermal expansion caused with the refractory and the bonding material. a_2; Absolute value of difference between thermal expansion modulus of the refractory and that of the bonding material. a; Invariable number determined by the investment. f; Porosities observed between the refractory and the bonding material. β; Variation of porosities caused by some out side factors. γ; Shrinkage caused by dehydration, heating at 200℃. | |||||||
