본문내용
1) O-A section
The stress and strain are proportional to the elastic deformation section, but there is no proportionality above the A point.
Therefore, the stress of point A is referred to as the proportional limit, and the limit load is calculated by dividing the original section.
The straight slope rate in the O-A section is called the elastic coefficient or the zero coefficient, which is the material constant.
2) A-B section
As the load increases above the proportional limit, the strain increases faster than the increase in stress. That is, the slope of the stress-strain line is reduced.
3) B-C section
This section is called the fully plastic section, which undergoes deformation without increasing the working load.
In short, the section that stretches easily without applying force.
4) C-D section
This section is called the modified hardening section, which increases hardness and strength of destruction by applying deformation to materials.
