Extremum principles for the energy-release problem of elastic-perfectly plastic body subjected to prescribed change of material properties

Two extremum principles for the energy-release increment in an elastic-perfectly plastic body subjected to prescribed change of the material properties are established. The principles, complementary to each other, can be directly applied to numerical calculations of upper and lower bounds for the en...

Beschreibung
Zusammenfassung:	Two extremum principles for the energy-release increment in an elastic-perfectly plastic body subjected to prescribed change of the material properties are established. The principles, complementary to each other, can be directly applied to numerical calculations of upper and lower bounds for the energy-release rate problems of fracture mechanics.
