The flow stress (σ) of an alloy varies with strain rate $$\left( \in \right)$$ as σ = 100 $${\left( \in \right)^{0.1}}$$ MPa. When the alloy is hot extruded from 10cm diameter to 5 cm diameter at a speed of 2 cm/s, the flow stress is
Identify the correct statements from the following: P. 0.2% yield strength of a material implies 0.2% of the yield strength. Q. Von-Misses yield criterion implies that yielding occurs when the distortion energy reaches a critical value. R. Radius of the cylinderical Von-Misses yield surface increases as the grain, size of a single phase material decreases. S. Tresca's yield criterion gives a circular cylinderical surface in the space of the three principal stresses.
