3 cards from this section. Quick, good the night before a test.
Define shear strain (γ) in your own words.
Think about the relationship between angles and perpendicular lines.
What does the strain matrix provide in terms of cylindrical coordinates?
Consider what happens to materials in cylindrical forms.
What does the term γ rθ represent?
Focus on the concept of angles and their relationships.
True or False: The strain matrix is limited to representing only tensile strains.
Think about other types of stress and strain we discussed.
Imagine a cylindrical rod under torsional loads. Calculate γ rθ when the angle between two radial lines is observed to increase from 90° to 95°.
Remember to analyze the initial and new angles for calculation.
Given a hollow cylinder located in a stress field, derive the impact of shear strain on its structural integrity as it undergoes loading.
Relate back to how internal and external loads affect material stability.
