Concept explainers

Strain energy

The term strain indicates the variation in an object's length, area, and volume when the object is subjected to an external force. The external force may be of normal, shear, moment, torque, etc. The strain in an object depends on the types of external force and cross-section of the object. Mathematically, the evaluation of strain can be obtained with the help of elastic constants.

Question

4. The maximum stress a human tendon can withstand is estimated to be 1200 MPa. If you were to test it for
rupture what load cell you should use (25ON or 5kN) what problems may occur if you select an incorrect load
cell.
5. The figure below is a J-shaped (or concave upward) stress-strain curve. What does a J-shaped stress
stain curve indicate about a material's response to stress and tendency to yield? Name two materials
that have J-shaped stress strain curves.

Question 1 You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt- chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows... A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some magnitude F produces a 7x10³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1H: Provide a brief rationale based on calculations used to support your answer. That is, how would you explain the behavior of the "new alloy" material to your design team?
