In this lesson, we will learn how to describe the properties of solid materials and the ways that they affect how objects respond to applied stresses.
What is a critical crack length most associated with?
What is the behavior of secondary creep?
How do brittle materials differ from ductile materials?
How do yield and fracture processes generally vary with temperature?
How does creep vary with temperature?
How do the processes leading to fracture differ from those causing yield?
How is strain rate related to primary creep?
In the linear-elastic regime, how does the stress required for fracture scale with the size
of the initiating defect?
How does creep deformation differ from cyclic fatigue?
For an end-loaded cantilevered beam, how does the bending moment depend upon position
along the length of the beam?
What is the most important property for a creep resistant material to have?
What design considerations can reduce or limit the effects of cyclic fatigue?
What is meant by the phrase "composite material" in engineering mechanics?
Under what condition is creep deformation particularly a concern?
