This research investigates the effects of reduction in the amount of plasticity in convex, concave, and flat geometries using plastic dissipation energy as the measure of plastic deformation imparted on the component.
The main form of energy dissipation is plastic dissipation.
In addition, the plastic dissipation energy was increased in the face-sheets.
The field parameters are specified from the condition of minimum plastic dissipation.
Plastic dissipation is allowed only at the interfaces between adjoining elements.
Crack propagation could induce severe material softening and deduce the plastic dissipation of the lattices.
Furthermore, parametric study is carried out to quantify effects of cracking resistances and plastic dissipation on the erosion rate.
Results show the plastic dissipation energy is proportional to the square of the strain energy release rate.
For rate sensitive materials, the amount of plastic dissipation typically depends on the rate at which the material is deformed.
This model provides a mechanism by which cleavage-type crack growth could proceed concomitantly with significant plastic dissipation.
The implication is that the separation process induces substantial plastic dissipation in the metal, consistent with the high interface toughness.
