The non-proportional loading of mild steel

Materials Research Proceedings
Abstract. The effect of proportional loading on formability has been extensively studied. However, non-proportional loading occurs frequently in a stamping operation and its impact on formability has been studied less. Non-proportional loading occurs in two areas of stamping: continuously during the draw stage of a complex geometry and discontinuously ...

Total deformation theory for non-proportional loading

International Journal of Pressure Vessels and Piping, 1998
Abstract This study presents a technique to apply a total deformation theory to non-proportional loading cases. A total deformation theory capable of analyzing a sequence of linear non-proportional load steps is proposed. Each linear loading path is defined with reference to its previous loading path, analogous to proportional loading.

Creep rupture under non-proportional loading

Acta Metallurgica, 1980
Abstract The quasi-empirical metallurgical theory of Dyson and McLean have been used to predict the behaviour of virgin Nimonic 80A tubes tested at 750°C under reverse torsion creep. The same theory has been modified to describe the behaviour of pre-strained Nimonic 80A tubes tested under conditions of constant and reverse torque.

The buckling loads of unbraced PR frames under non-proportional loading

Journal of Constructional Steel Research, 2002
Abstract This paper discusses the elastic stability of unbraced frames with partially restrained (PR) connections under non-proportional loading drawing upon the concept of storey-based buckling. The problem of determining critical elastic buckling loads of the frames under non-proportional loading is expressed as a pair of minimization and ...
