MecMovies 4.0 : M13.6: Principal Stresses from Rosette Data

After reducing the strain gage rosette data, the following normal and shear strains have been determined:

ε_x = +770 με

ε_y = -350 με

γ_xy = +1,940 μrad

The corresponding stresses in the x and y directions can be determined from the strain values through the use of the following generalized Hooke's Law stress-strain relationships.

σ_{x} = \frac{E}{(1 - ν^{2})} (ε_{x} + {νε}_{y}) σ_{y} = \frac{E}{(1 - ν^{2})} (ε_{y} + {νε}_{x}) τ_{xy} = {Gγ}_{xy}
