Effective determination of cyclic-visco-plasticity material properties using an optimisation procedure and experimental data exhibiting scatter [PDF]
, 2013 It may be inevitable in the design and analysis of most high temperature components (such as power industry pipe work) that variations in load and/or temperature will occur in normal operation.

Study on Blade Fatigue Life of Rotating Power Machinery
MATEC Web of Conferences, 2016 The linear damage model (LDM) is widely applied in engineering calculation, but it does not consider the relationship between damage variable and load parameters.

Steady-state and transient Zener parameters in viscoplasticity: Drag strength versus yield strength [PDF]
A hypothesis is put forth which enables the viscoplastician to formulate a theory of viscoplasticity that reduces, in closed form, to the classical theory of creep. This hypothesis is applied to a variety of drag and yield strength models. Because of two

Model coupling friction and adhesion for steel-concrete interfaces
, 2009 The interface behaviour between steel and concrete, during pull-out tests, is numerically investigated using an interface model coupling adhesion and Coulomb friction. This model, first developed by Raous, Cang\'emi, Cocou and Monerie (RCCM), is based on

On the thermodynamics of stress rate in the evolution of back stress in viscoplasticity [PDF]
A thermodynamic foundation using the concept of internal state variables is presented for the kinematic description of a viscoplastic material. Three different evolution equations for the back stress are considered.

Probabilistic framework for multiaxial LCF assessment under material variability [PDF]
, 2017 The influence of material variability upon the multiaxial LCF assessment of engineering components is missing for a comprehensive description. In this paper, a probabilistic framework is established for multiaxial LCF assessment of notched components by ...
