If the tensile specimen is not cylindrical rod shaped but a flat rectangular plate, how do
you expect necking to occur in this type of specimen?
The following results were obtained in a tensile test on a mild steel specimen of original diameter 28 mm and gauge length 56 mm.
Load at limit of proportionality : 96 kN
Extension at 96 kN load : 0.068 mm
Load at yield point : 105 kN
Maximum load : 170 kN

- Explain Flexure Test of Small, Clear Specimen (ASTM D143) ?arrow_forwardTensile test is a method to investigate the elasticity of a material. A test specimen is placed between two clamps and these clamps will move in opposite directions, hence straining the test specimen. This experiment will yield a stress-strain curve that shows each of the stages of the specimen for every load is applied. With an aid of sketching diagrams, describe the stages that the specimen experiences before it breaks, and relate it with the stress-strain curve. It is expected that each stage comes with a sketching of the specimen and explanation of the current stage.arrow_forwardWhen the true strain equals 0.14 and the true stress equals 355 MPa, the tensile test specimen starts to neck.
