Stress at point of failure

Fracture Strain

Modulus of elasticity of the sample

A tensile test is performed on a 10mm thick sample of PVC of width 15mm. The sample was tested to fracture at room temperature and which point the sample had a total length of 74mm and the force measured was 30kN. Given that the original length was 70mm, calculate the following to 2 decimal places: a) The stress at the point of failure = Mpa 2 marks Unanswered b) The fracture strain =
