A tensile test specimen has a gage length = 50 mm and diameter = 20 mm. Yielding occurs at a load of 137900. The corresponding gage length = 51 mm, which is the 0.2 percent yield point. The maximum load of 258100 N is reached at a gage length = 62.8 mm. Determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength.
A steel component must support a uniaxial tensile load. The component has three cracks of size: 5 mm, 2.5 mm and 1 mm as shown in the diagram below. The size of the component is substantially larger than the crack size.
