A 13 mm-diameter tensile specimen has a 50 mm gauge length. The load corresponding to the 0.2 percent offset is 6800 kg and the maximum load is 8400 kg. Fracture occurs at 7300 kg. The diameter after fracture is 8 mm and the gauge length at fracture is 65 mm. a) Calculate the standard mechanical properties of the used specimen in the tension test, first determine the standard properties and then calculated them? This includes computation each of: Yield strength. Ultimate tensile strength. Fracture stress. Ductility (percent of elongation and reduction in cross section area). b) If E= 207 GPa, estimate the elastic recoverable strain at maximum load? c) By using the same conditions of the above test, Discussion the possibility to replace the metallie sample with ceramic sample?
