Theoretical backgrounds of durability analysis by normalized equivalent stress functionals [PDF]
, 2003 Generalized durability diagrams and their properties are considered for a material under a multiaxial loading given by an arbitrary function of time. Material strength and durability under such loading are described in terms of durability, safety factor ...

A kinetic comparison of back-loading and head-loading in Xhosa women [PDF]
, 2011 The purpose of this study was to compare the kinetic responses associated with ground reaction force measurements to both head-loading and back-loading in a group of Xhosa women. Altogether, 16 women were divided into two groups based on their experience
