WebConservation of angular momentum for a continuum requires that the Cauchy stress satisfy. σji = σij. i.e. the stress tensor must be symmetric. Derivation: write down the equation for balance of angular momentum … Weba borehole strain sensor. We will also review the Cauchy stress tensor and the conservation laws that generalize conservation of mass and momentum to continuous media. Last, we will consider constitutive equations that relate the stresses acting on a material element to the resultant strains and/or rates of strain.
