Answer: According to Haigh’s Theory Yield Locus is an Ellipse

Haigh’s Theory describes that in a member the yielding or failure occurs at a point when the strain energy per unit volume in a bi-axial stress system achieves the limiting strain energy (i.e. strain energy at the yield point ) per unit volume.

Haigh was born on 8 July 1884 in Edinburgh, Scotland and died on 18 January 1941 at the age of 56 at Greenwich, London, England.
