Explain why the concept of shear ductility is revised through a
maximum capacity to shear and why this is a function only of the
strength of the concrete.
Discussed tax vs financial accounting. A concept introduced this
week is material weakness. Can you explain this concept as related
to tax and financial accounting?
(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.
