Analysis of tensile test results of universal testing machine

existUniversal testing machineAmong various tests, tensile test is the basic material detection, which is generally completed by a universal testing machine. The specific operation process is to slowly apply loads at both ends of the sample, causing the test to be subjected to axial tension locally, causing the sample to extend in the axial direction, and usually proceed until it is broken. Tensile strength and plastic characteristics of the data can be measured through tensile experiments. The tensile samples must meet the tensile experimental requirements of relevant national and industry standards for divergent data. Tensile experimental curve Stress-strain tensile curve.

The stretching curve can be divided into four stages:

1. 10ab—Elastic deformation stage. The PP value corresponding to point a is called proportional limit negative point b is called the Pe value corresponding to point b is called elastic limit load (resistance that does not undergo eternal deformation) 0—Segment a ÄL proportional to p Linear stage. The extreme microplastic deformation of segment a—segment b (0.001-0.005%)

2. (bcd)-Captification stage c Point reference point corresponds to PS c-d waveform segment "platform".

3. dB-average plastic deformation stage Point B corresponds to the intensity limit load (acceptable load) of the Pb value data.

4. BK-partial concentrated deformation stage (neck) point K is the fracture load corresponding to the Pk value
