Measurement and prediction of the residual stress field generated by side-punching

Article Abstract:

Side-punching is proposed as a method of introducing a well-defined residual stress field into a laboratory-sized test specimen. Side-punching consists of simultaneously indenting opposite faces of a plate of material with rigid tools using sufficient force to cause localized yielding over a finite-sized volume of material adjacent to the punching tools.

Creep relaxation of residual stresses around cold expanded holes

Article Abstract:

Experimental measurement and finite element prediction of cold expansion residual stresses and their redistribution after creep, with and without additional mechanical load are studied. The study reveals that the case where creep relaxation occurs without applied load shows the least compressive residual stress.

The effect of graded strength on damage propagation in continuously nonhomogeneous materials

Article Abstract:

A damage model developed by Johnson and Holmquist is incorporated in a dynamic finite element code. This code is then used to study in detail the propagation of damage in a material with graded intact strength, a particular region of the domain can be protected from maximum damage.
