DISCUSSIONS:

1. Draw a typical stress-strain diagram and indicate what are meant by peak strength and residual strength .

2. What are the limitations of direct shear stress? 3.

Draw the Mohr’s circle foe failure for a direct shear stress test and mark the failure plane, a major principle plain and minor principal plain.

4. If the test is under a normal stress of 2.5 kg/cm2 , find the shear load at which the soil will fail.(Use ? found from the test).

5. State the Mohr – Cuolomb criteria for shear strength in terms of the effective stresses

6. What are the advantages of the direct shear test over the triaxial test?

: In mechanics, this quantity represents the total area under the stress–strain diagram, and therefore it indicates the maximum amount of strain energy per unit volume the material can absorb just before it fractures. Certainly this becomes important when designing members that may be accidentally overloaded. Which type of modulus is it? Describe it.

(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.
