Define engineering failure. Give two examples of the following: a) Designing to avoid failure and b) Designing to achieve failure.

Solution

An engineered system fails when it stops working. The majority of engineering failures are caused by fatigue. Fatigue failure is defined as the tendency of a material to fracture by means of progressive brittle cracking under repeated alternating or cyclic stresses of an intensity considerably below the normal strength.

While designing to avoid failures, standardize suppliers for devices where possible. This minimizes the number of interfaces to be dealt with by end users.

Use materials that can withstand the loads and environments associated with operation.

While designing to achieve failures, engineers try to find the impact of damage caused due to failure so that in future such failures can be avoided.
