A cylindrical specimen of steel having an original diameter of 12 mm is tensile tested to fracture and found to have an engineering fracture strength of 460 MPa. if its c/s diameter at fracture is 10 mm, what is the true stress at fracture?
The highest stress that a material can withstand for a specified length of time without excessive deformation is called
