Abstract:

In solid explosive materials, the holes filled with gas can portray explosion-triggering hot spots. We explore the form factor on the generation of the hot spots. As a result, we consider the Eshelby approach in the two-dimensional problem of determining the thermoelastic field of an elastic plane weakened by an elliptic hole and the field with liquid or gaseous media.
