The transformation equations for plane stress can be represented in a graphical format known as mohr s circle. Mohr s circle is a geometric representation of the 2d transformation of stresses and is very useful to perform quick and efficient estimations, checks of more extensive work, and other such uses. Mohrcoulomb theory is a mathematical model see yield surface describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress. Section 2 introduces a little known enhancement to mohrs circle namely, the pole po int that rectifies this prob lem. Published under licence by iop publishing ltd journal of physics.

Mohr s circle, invented by christian otto mohr, is a twodimensional graphical representation of the transformation law for the cauchy stress tensor mohr s circle is often used in calculations relating to mechanical engineering for materials strength, geotechnical engineering for strength of soils, and structural engineering for strength of built structures. Mohr s circle for plane stress university of arizona.
Chapitre 4 plasticite, resistance au cisaillement, stabilite. Mohrs circle, invented by christian otto mohr, is a twodimensional graphical representation of. Brannon mohrs circle and more circles university of utah. This representation is useful in visualizing the relationships between normal and shear stresses acting on various inclined planes at a point in a stressed body. Mohr developed a generalised form of the theory around the end of the 19th century. Most of the classical engineering materials somehow follow this rule in at least a portion of their shear failure envelope. The mohr stress diagram a means by which two stresses acting on a plane of known orientation can be plotted as the components of normal and shear stresses derived separately from each of the two stresses. The mohr circle is thus an elegant way to determine the shear and normal stresses for a pair of stresses oriented obliquely to the plane. Those who already know mohrs circle may recall that an angle gets doubled when portrayed in mohrs circle, which can be very confusing.
