The meaning of STRESS-STRAIN CURVE is a chart or curve showing the relation between the load or stress on a structural member or specimen of material and the corresponding strain or deformation.
显示为金属材料典型的应力- 应变曲线图,在此曲线上包含着一段线性比例关系的区域,此区域的材料行为符合所谓的虎克定律(Hook’sLaw) 弹性行为。此弹性区域的材料模数( 杨氏模数,弹性模数) 为一常数定值;所谓模数Modulus=(stress)/(strain) 即为应力-应变曲线上的对应斜率,在此弹性区域上可以藉由简单的应变量值与起始...

Theoretical analysis of the stress–strain curve for elastic-perfectly plastic polycrystalline material has shown that only the part of stored energy can be calculated from the stress–strain curve. This part is the energy stored during non-homogeneous plastic deformation. The results of such ...
A convenient approximate solution(1, 2) for the design of components constructed from polymers employs the use of "isochronous" stress–strain curves and a "secant modulus" Es(t). If a series of creep tests are carried out to produce a set of strain-time curves at various stress levels a...
stress–strain curveIn recent years, the study of polymer/clay nanocomposites has attracted major research and commercial interests due to their superior mechanical and thermal properties to those of the neat polymers. Numerical modelling is an advantageous approach to understand the material behaviour. ...

Ethylene (co) polymers, and laminate and hollow molding made by using the same (d) relationship between stress (σ) and maximum stress (σ max) in a stress-strain curve in uniaxial stretching, (e) the ratio of sample diameter to initial sample diameter and the time for sample breakage dur...
The stress–strain curve (SSC) prediction for additively manufactured as-build metal materials with laser powder bed fusion (LPBF) is a lengthy and tedious process. It involves the sophisticated representative volume element (RVE) reconstruction of complex experimental microstructures for subsequent state...
Stress-strain curve of a ductile material This is also true for region AB, except that the material in this region doesn’t obey Hooke’s law, a fact one can easily discern from its non-linear shape. Point A is called the proportional limit because beyond this point, stress and strain ...
