Ductile and brittle materials behave differently in compression test as well. The compression test is conducted on short cylindrical specimens placed between parallel plates.
塑性和脆性材料在压缩试验中表现的特性是不相同的。压缩试验是把短圆柱形试件放在两平行平板之间进行的。

The backlight photography with single sample was used to measure the true stress-strain of the ductile material after necking in tensile test.
本文采用单试样逆光拍照法对延性材料拉伸试验缩颈后的真实应力-应变进行了有效的测量。
