Maximum stress that a material can resists is called yield stress. True or False?
Maximum stress that a material can resists is called yield stress.
True or False?
Homework Answers
At yeilding point the substance looses its elasticity so it is also called as elastic limit.
Beyond this point also if you apply stress the material can resists but hooks law is not valid. The material after yield stress turns to plastic deformation, and finally to a breaking point. Upto this point the material can resists to the load.
so answer is False

Failure criterion The yield stress of a material is 40 MPa. This material is subjected to the maximum normal stress and the minimum normal stressz--0.350. Determine the magnitude of 01 MPa that will cause yielding according to the maximum shear stress criterion (rounding to two decimal places).

The maximum stress that a brittle material can safely support in service can be difficult to specify because it can be affected by: The surface finish of the material The temperature of the material in service The presence of corrosive agents in the service environment All of the above None of the above

5. Circle true of false for the following statements: T The resistance ofa material to indentation is a qualitative indication of its strength. Ultimate tensile strength is the maximum stress on the engineering stress strain T F curve Young's modulus is closely related to the bonding energies of the atoms. T A bend test is used for brittle materials to describe the material's strength. T F Ductility is frequently quantified as the percent elongation at failure T F tr.
