弯曲试验技术相关的,翻译英文部分,谢谢
For this test, specimens with thickness a and width b are to be prepared, the edges of which may be rounded on the tension side to a radius of 1-2 mm.For plates and sections the specimen thickness a is equal to the product thickness t. For product thicknesses thicknesses  exceeding 25 mm the thickness may be reduced by machining the compression side of the bend specimen to not less than 25 mm.
To perform this test, the test specimen is bent in a continuous operation as shown in Figure 2.13 and using a mandrel of specified radius D/2 until the prescribed bending angle α is reached or the initial incipient fracture occurs. For normal strength steels D/2 = 2 ⋅ a, for higher strength steels D/2 = 3 ⋅ a. The test shall be satisfactory if the prescribed bending angle is achieved without incipient fracture. If, when the specimen is unclamped, it springs back, the bending operation need not be repeated.

为试验准备厚度a、宽度b的样件,拉伸侧的边缘可倒半径1-2mm的圆角。对于板和截面,试件厚度a等于产品厚度t。产品厚度超过25mm时,可以通过加工挤压侧将厚度减到小于25mm。
根据图2.13所示的连续操作弯曲试件,使用半径D/2的芯轴直到达到预定的弯曲角a或发生早期断裂。对普通强度钢D/2=2⋅a,对高强度钢D/2=3⋅a。如果达到预定弯曲角而没有出现早期断裂,试验满足要求。如果装夹松开,试件弹回,不需要重复弯曲操作。
