test-piece

A test-piece is shaped into a beam of about 20 cm length and its upper surface is highly polished. The test-piece is bent convex upwards; on that occasion one had better plan the maximum bending stress to be about 20 bar or less.

试件加工成20cm长的梁，并高度磨光其上表面，把它弯成向上凸，其最大弯曲应力宜为20bar或稍小一些。

Under the full consideration on the interaction of the temperature field, the microstructure field and the internal stress field of a quenching test-piece, the numerical calculation models of the three kinds of fields of a shaft-type test-piece are set up.
