Example of a non-sparking tool made of beryllium copper. Beryllium copper is a non-ferrous alloy used in springs, spring wire, load cells, and other parts that must retain their shape under repeated stress and strain. It has high electrical conductivity and is used in low-current contacts for batteries and electrical connectors.
Stress–strain curve for brittle materials compared to ductile materials. Some common characteristics among the stress–strain curves can be distinguished with various groups of materials and, on this basis, to divide materials into two broad categories; namely, the ductile materials and the brittle materials.

The Ramberg–Osgood equation was created to describe the nonlinear relationship between stress and strain—that is, the stress–strain curve—in materials near their yield points. It is especially applicable to metals that harden with plastic deformation (see work hardening), showing a smooth elastic-plastic transition.
Young's modulus is the slope of the linear part of the stress–strain curve for a material under tension or compression.. Young's modulus (or Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise.
As the load increases, the machine records the corresponding deformation, plotting a stress-strain curve that would look similar to the following: True stress-strain curve for a typical specimen. The compressive strength of the material corresponds to the stress at the red point shown on the curve.
The area under the linear portion of a stress–strain curve is the resilience of the material. In material science, resilience is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading.
Other models may also include the effects of strain gradients. [3] Independent of test conditions, the flow stress is also affected by: chemical composition, purity, crystal structure, phase constitution, microstructure, grain size, and prior strain. [4] The flow stress is an important parameter in the fatigue failure of ductile materials.
The most common example of this kind of material is rubber, whose stress-strain relationship can be defined as non-linearly elastic, isotropic and incompressible. Hyperelasticity provides a means of modeling the stress–strain behavior of such materials. [2] The behavior of unfilled, vulcanized elastomers often conforms closely to the ...
