**Lecture7-Sept16 Nc State University**

In engineering, the stress-strain curve is a very valuable tool. With one simple graph an engineer can understand many properties of a material under load (applied force). Specifically the stress-strain curve shows the relationship of strain to stress for certain materials â€¦... Ultimate tensile strength (UTS) is the maximum stress that a material can withstand while being stretched or pulled. The ultimate tensile strength of a material is calculated by dividing the cross-section area of the material tested by the stress placed on the material, generally expressed in terms of pounds or tons per square inch of material.

**Lecture7-Sept16 Nc State University**

The region in stress-strain diagram from O to P is called the elastic range. The region from P to R is called the plastic range. Yield Point Yield point is the point at which the material will have an appreciable elongation or yielding without any increase in load. Ultimate Strength The maximum ordinate in the stress-strain diagram is the ultimate strength or tensile strength. Rapture Strength... The maximum value of the elastic strain energy is the resilience, which occurs when the stress in the axial member reaches the yield strength (thus the system is no longer elastic): Fatigue The standard fatigue test (zero mean stress) has a strain-time history graph as shown at right.

## How To Find Yield Strength From Stress Strain Graph

### Click a point on the stress-strain curve. Arrow-key over to the point right at the intersection with the offset line. Zoom in really closely. Hold cursor over box. Note data point. Display in text box on graph.

- 5/02/2012Â Â· Its the first region in the graph and to calculate this pick a point in the elastic region and solve for stress/strain. 2. Yield Stress: This is the point where plastic deformation occurs, in other words anything up to this point is elastic deformation.
- When we load some material, and plot a stress-strain curve, the point in that curve where elastic limit is reached and the body starts to undergo plastic deformation (permanent deformation), is called yield stress or yield strength of that material.
- Shear stress-strain curve (left) and corresponding viscosity-stress curve (right) for materials with and without a yield stress. Stress Growth A constantly increasing stress is applied with a stress ramp test and the resultant strain rate or shear rate monitored with time.
