I'm getting approximations within 5% of the actual values. Does that sound about right?
Mohr's circle is a graphical method used to represent the stress state at a point in a material. It is a plot of the normal stress (σ) on the horizontal axis and the shear stress (τ) on the vertical axis.
Mohr's circle assumes that the material being analyzed is homogeneous, isotropic, and linearly elastic. It also assumes that the stress state is at a point and not varying over an area.
Mohr's circle is a relatively accurate graphical method for representing stress states. However, it is not exact and may introduce some error due to the assumptions made and the approximation of the stress state as a point.
One major limitation of Mohr's circle is that it can only be used for two-dimensional stress states. It also does not account for factors such as material nonlinearity, plastic deformation, or stress concentrations.
Mohr's circle can be used to determine the principal stresses at a point by finding the points where the circle intersects with the horizontal axis. The corresponding values on the vertical axis represent the maximum and minimum shear stresses, and the distance between these points represents the difference between the two principal stresses.
