Mohr's Circle Plane Normal Strain Y Direction

Mohr's circle is a two-dimensional graphical representation of the transformation law for the Cauchy stress tensor. Normal strain is a description of deformation in terms of relative displacement of particles in the normal direction in the body that excludes rigid-body motions.

The normal strain in a new y direction increases with the normal strains in the x and y directions (though a larger normal strain in the y direction will increase it more). Decreased shear strain in the x\[Hyphen]y coordinates will also increase normal strain in the new y direction. The angle of the new y direction also modifies the normal strain in the new y direction.

Formula

QuantityVariable[Subscript["ε", Superscript["y", "′"]], "Unitless"] == -(Cos[2*QuantityVariable["θ", "Angle"]]*(QuantityVariable[Subscript["ε", "x"], "Unitless"] - QuantityVariable[Subscript["ε", "y"], "Unitless"]))/2 + (QuantityVariable[Subscript["ε", "x"], "Unitless"] + QuantityVariable[Subscript["ε", "y"], "Unitless"])/2 - (QuantityVariable[Subscript["γ", "x⁣y"], "Unitless"]*Sin[2*QuantityVariable["θ", "Angle"]])/2
