Engineers have long used stress-strain curves to uncover a host of material properties including elastic limit, elastic and plastic ranges, yield point, ultimate and rupture strengths, and the ...

Nominal stress/strain curves for Al 2 O 3 (a), a low carbon steel (b), a cross-linked natural rubber (c), and a the polymer, polymethyl-methacrylate, tested at 122 C are shown inthe figure opposite.

For the Haynesville sample, the modulus was 22.5GPa and the hardness was 0.51GPa. By assuming a Poisson’s ratio of 0.25 and negligible work-hardening, stress-strain curves were deduced from these ...

Moreover, the quality of the test results is typically not satisfactory, requiring signal damping and curve smoothing to make them usable. Since tensile steel stress-strain data at dynamic conditions ...

Young's modulus is, therefore, the slope of the stress/strain curve in the initial linear elastic region. When an isotropic elastic material experiences a uniaxial stress, its volume is not conserved ...

The research, published today (26 th October) in the journal Science, demonstrates experimentally, for the first time, that the electronic and mechanical properties of a metal are connected.
