A Review of Creep Deformation and Rupture Mechanisms of Cr-Mo Alloy for the Development of Creep Damage Constitutive Equations under Lower Stress
This paper presents a review of creep deformation and rupture mechanisms of low Cr-Mo alloy for the development of its creep damage constitutive equations under lower stress. The most popular Kachanov-Robatnov-Hayhurst (KRH) formulation was not necessarily developed and calibrated for low stress and cannot depict the creep strain accurately under multi-axial state of stress due to the three-dim...
متن کاملA constitutive model for unsaturated cemented soils under cyclic loading
On the basis of plastic bounding surface model, the damage theory for structured soils and unsaturated soil mechanics, an elastoplastic model for unsaturated loessic soils under cyclic loading has been elaborated. Firstly, the description of bond degradation in a damage framework is given, linking the damage of soil’s structure to the accumulated strain. The Barcelona Basic Model (BBM) was cons...
متن کاملSpeech Recognition under Stress Condition
The objective of this work is to conduct a speech recognition study and evaluate the performance of the same under stressed condition. The speech recognition study is conducted both in isolated word recognition and keyword spotting approaches. The word models are built during training using speech collected from neutral condition. During testing these models are tested with speech signals colle...
متن کاملA Nonlinear Creep-damage Constitutive Model of Mudstone Based on the Fractional Calculus Theory
During the flood development in an oil field, the creep characteristic of mudstone is one of the important factors causing casing damage. In this study, based on the theory of fractional order differential and taking into account the creep damage evolution rules, a fractional nonlinear creep-damage model is proposed to reflect the instantaneous deformation in loading processes and the accelerat...
متن کاملReview of creep deformation and rupture mechanism of P91 alloy for the development of creep damage constitutive equations under low stress level
This paper presents a review of creep deformation and rupture mechanism of P91 alloy for the development of its creep damage constitutive equations under lower stress level. Creep damage is one of the serious problems for the high temperature industries and computational approach (such as continuum damage mechanics) has been developed and used, complementary to the experimental approach, to ass...
