(c) Draw a schematic graph of resolved shear stress versus shear strain for a single crystal of a pure metal. Clearly label the point of the critical resolved shear stress and the three subsequent stages of dislocation behaviour. Describe these three stages. (d) Explain why the critical resolved shear stress is much lower than the theoretical strength, based on the force required to break atomic bonds within the structure.

Derive the equation for the shear strain in terms of the mobile dislocation density and velocity

Plot the shear flow distribution around the section, with values in terms of S and a

Fig. 8 shows the regular hexagonal cross-section of a thin-walled beam of sides ‘a’ and constant wall thickness t. The beam is subjected to a transverse shear force S, its line of action being along a side of the hexagon, as shown. Find the rate of twist of the beam in terms oft, a, S and the shear modulus G. Plot the shear flow distribution around the section, with values in terms of S and a

At mechanics of metal cutting, I cannot understand the reason why the shear angle is smaller when the cutting speed is slow. can you explain this to me?

For each of the following pairs of polymers, plot and label schematic stress-strain curves on the same graph [i.e. make separate plots for parts (a), (b) and (c)]. (a) Polychloroprene rubber having a number-average molecular weight of 100,000 g/mol and 15% of available sites cross-linked; liner polypropylene having a number-average molecular weight of 150,000 g/mol.

A stress is suddenly applied to a muscle and then held constant while strain and strain‐rate are measured (see right figure). The phenomenon explaining the measured strain is called __________________. As the stress is maintained and the strain reaches steady state __________________ stresses dominate the total stress. a. Stress‐relaxation, elastic b. Stress‐relaxation, viscous c. Creep, viscous d. Creep, elastic
