Stress freezing method

Japanese: 応力凍結法 - おうりょくとうけつほう
Stress freezing method

…In this case, the relationship I = I 0 sin 2 π N holds. The stress freezing method is usually used for three-dimensional photoelasticity to investigate the stress of three-dimensional objects. With a load applied to a three-dimensional model, the model material is heated to a temperature (freezing temperature) specific to the material to create a stress state in rubber-like elasticity. If the model is slowly cooled to room temperature while still under load, the stress state is frozen within the model even after the load is removed, and this state is preserved even if the model is then thinly sliced. …

*Some of the terminology that refers to the "stress freezing method" is listed below.

…このときはII0sin2πNの関係が成立する。 三次元物体の応力を調べる三次元光弾性には通常応力凍結法が用いられる。三次元モデルに負荷を加えたまま,そのモデル材料に特有な温度(凍結温度)まで加熱してゴム状弾性時の応力状態とし,負荷したままこれを室温まで徐冷すると,負荷を取り除いても応力状態がモデル内に凍結され,その後このモデルを薄くスライスしてもその状態が保存される。…
