Physical Meaning of von-mises yielding criteria is that yielding occurs when the _____________ reaches a critical value. Correct Answer distortion energy

Physical Meaning on von-mises yielding criteria is that yielding occurs when the distortion energy reaches a critical value. The distortion energy is part of strain energy per unit volume that is involved in a change of shape as opposed to a change in volume.

Tresca or maximum-shear stress criteria assumes that yielding occurs when the maximum shear stress reaches a value of the shear stress in the uniaxial tension test. Assume the principal stress being σ1, σ2, σ3 where σ1 is largest, and σ3 is the smallest principal stresses. Find the value of minimum shear stress to cause yielding, given that yield stress in tension is equal to σo?

The questions given below are in the form of a statement followed by assumptions 1 and 2. You may assume that everything stated in the statement is true, then consider the two assumptions and decide which of them logically follows, beyond a reasonable doubt, from the information in the statement. Statements: The policy of subsidizing high-yielding varieties of seeds (HYVs) has been adopted in the five-year plans in India. Assumptions: 1. High Yielding Variety Seeds (HYV) will increase productivity in the agriculture sector. 2. Normal seeds are relatively less productive as compared to high-yielding variety (HYV).
The yielding criteria are primarily empirical relations. Pure hydrostatic stress causes the yielding in continuous solid.
