However, the question still remains as to how to deal with the singularity problem and the answer lies in dealing with the elastic strain energy as opposed to focusing on the stress level.
To stick or not to stick: guide to adhesion measurement for the layman
As the high elastic strain energy accumulated in the rock masses is greater than the energy consumed by rock failure, imbalance of the rock mass structure occurs and the excess energy causes the rock to explode and emitted rock debris", he explained.

Investigating effect of steel plate shear wall opening change on amount of equivalent viscous damping
The conditions for this mechanical instability depend on the strength to break the fibril and the intensity of the elastic strain energy that is the potential energy accumulated in the structure until the fibril is broken.

Under some circumstances these perturbations of the stress field can trigger events which release enormous amounts of elastic strain energy that was stored within the deformed rock mass.
Using passive microseismic monitoring for site safety
This numerical approach involves minimizing the elastic strain energy for a frictionless interfacial contact subject to the condition of all contact pressures being compressive and therefore greater than zero, other than for regions of no-contact.

On the measurement of fracture toughness of soft biogel
This was termed the tearing energy by Rivlin and Thomas (see reference 1), and it is defined by [Mathematical Expression Omitted] where U is the total elastic strain energy stored in the sample, A is the area of one fracture surface of the crack (in the unstrained state), and the partial derivative indicates that the sample is considered at a fixed deformation so the external forces do no work (strain controlled rather than load controlled deformation).
Fatigue and fracture of elastomeric materials
The latter point leads to substantial simplifications when large deformations, including large rotations especially, are considered, with negligible differences obtained with respect to significantly more complex hyperelastic laws (where an elastic strain energy function is defined) when elastic strains keep small, as is the case in the applications considered here.

However, the stress-strain evolution followed from the first loading, achieved under low strain rate, can be described using a hyperelastic formalism derived from elastic strain energy potential (24), (25).
