General Equations of Plane Strain
Learning Goal:
To become familiar with the general equations of plane
strain used for determining in-plane principal strain,
maximum in-plane shear strain, and average normal
strain.
The state of strain at a point has components of
€ = 400.0 × (10-6), y = −215.0 × (10-6), and
Yzy = 200.0x (10–6).
Part A - Equivalent in-plane strains on the oriented element
Determine the equivalent in-plane strains on an element rotated counterclockwise at an angle of 0 = 60.0°
Express your answers, separated by commas, to three significant figures.
