Stress strain curve is a behavior of material when it is subjected to load. In this diagram stresses are plotted along the vertical axis and as a result of these stresses, corresponding strains are plotted along the horizontal axis. As shown below in the stress strain curve. From the diagram one can see the different mark points on the curve. stress strain curve of different metals In a tension test, true strain is less than engineering strain. Thus, a point defining true stressstrain curve is displaced upwards and to the left to define the equivalent engineering stressstrain curve. The difference between the true and engineering stresses and strains will increase with plastic deformation. At low strains (such as elastic deformation), the differences between the two is negligible. Two important effects necessary to understand the true stress are the effects of strain

Different Metals Respond to Strain in Different Ways. This deformation is a visible sign of metal strain. In metallurgy, strain can be defined as the deformation of a metal due to stress. In other words, it's a measure of how much a metal has been stretched or compressed when compared to its original length. stress strain curve of different metals

Stress strain curve is the plot of stress and strain of a material or metal on the graph. In this the stress is plotted on y axis and its corresponding strain on the xaxis. After plotting the stress and its corresponding strain on the graph, we get a curve, and this curve is called stress strain curve or stress strain diagram. Feb 01, 2017  True stress and Engineering stresses are a bit different. Consider the figure showing stressstrain relationships of a midsteel. image of Materials 8th Edition The above figures are the stress vs. strain graph This may be calculated as the area under the entire stressstrain curve (from O to R). The toughness of a material is its ability to absorb energy without causing it to break. Working Stress, Allowable Stress, and Factor of Safety Working stress is defined as the actual stress of a material under a given loading. stress strain curve of different metals The stressstrain diagram is generally accepted as the plotted results of a tensile test completed under carefully controlled conditions on a speciman of a metal. The stressstrain diagram important for design engineers in that it establishes the physical properties of the material under test including the yield strength, the ultimate strength, the elongation at fracture, the elastic limit etc.
