How To Draw Stress Strain Curve For Concrete

Stress Strain Curve Explanation

Stress strain curve is a behavior of material when it is subjected to load. In this diagram stresses are plotted forth the vertical centrality and as a result of these stresses, corresponding strains are plotted along the horizontal axis. Equally shown below in the stress strain bend.

Stress Strain Curve

From the diagram ane can run into the dissimilar mark points on the curve. Information technology is because, when a ductile material like mild steel is subjected to tensile test, then information technology passes diverse stages before fracture.

These stages are;

Proportional Limit
Rubberband Limit
Yield Betoken
Ultimate Stress Bespeak
Breaking Bespeak

Proportional Limit

Proportional limit is indicate on the curve upwardly to which the value of stress and strain remains proportional. From the diagram point Pis thecalled the proportional limit betoken or it tin can also be known as limit of proportionality. The stressup to this bespeak tin be as well be known equally proportional limit stress.

Hook's police of proportionality from diagram tin be divers between bespeak OP. It is so, considering OP is a direct line which shows that Hook'due south police of stress strain is followed upwardly to indicate P.

Elastic Limit

Elastic limit is the limiting value of stress up to which the material is perfectly elastic. From the curve, betoken Eastward is the elastic limit bespeak. Material volition return dorsum to its original position, If it is unloaded before the crossing of point Due east. This is so, because cloth is perfectly elastic up to point E.

Yield Stress Indicate

Yield stress is defined as the stress after which fabric extension takes identify more than quickly with no or fiddling increase in load. Signal Y is the yield signal on the graph and stress associated with this bespeak is known equally yield stress.

Ultimate Stress Point

Ultimate stress point is the maximum strength that material have to bear stress before breaking. It can also be defined as the ultimate stress respective to the peak point on the stress strain graph. On the graph point U is the ultimate stress bespeak. Subsequently point U material accept very infinitesimal or zero strength to face further stress.

Breaking Stress (Point of Rupture)

Breaking point or breaking stress is indicate where force of material breaks. The stress associates with this point known equally breaking force or rupture force. On the stress strain curve, point B is the breaking stress point.
