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.

6. Airplane components often have a “stressed skin" construction, which consists of a thin sheet of aluminum in tension connected to the structure with rivets (i.e. pins that go through circular holes). a. If the aluminum skin is subject to a far-field biaxial tension of σ = 100 MPa and has a yield strength of σ = 210 MPa, will the rivet cause the sheet to yield? b. What is the strain through the thickness (z-direction) at the top-most edge of the hole? What does this mean is happening to the plate at that point? c. If a crack of length a = 1 mm forms at the side of the hole, will the plate fracture? How about if the crack is a = 3 mm? Take the aluminum to have a fracture toughness of K₁c = 15 MPa√m, and take the geometric stress concentration factor to be Y = 1.12. 50 = a
