In the realm of multi-axial ratcheting, a step by step mathematical approach is developed for the parameter determination of decomposed kinematic hardening rules. For this purpose, key characteristics are mathematically derived for these hardening rules under multi-axial loading. These characteristics are then utilized to develop expressions which relate the loading history to the accumulated p...

Abstract This study has considered the behaviour of granular materials subjected to drained cyclic loading under constant mean effective stress. Using discrete element method, cubical, isotropically compressed samples were 50 cycles at different values stress ( $$p' =$$ p ′ </mml:ms...

We examine the accelerating ‘obesity epidemic’ in the US from the perspective of recently developed theory relating a cognitive hypothalamicpituitary-adrenal axis to an embedding ‘language’ of structured psychosocial stress. Using a Rate Distortion argument, the obesity epidemic is found to represent the literal writing of an image of a ratcheting pathological social hierarchy onto the bodies o...
