Effects of damage distribution on evolution
, 1997 Recent micromechanically inspired phenomenological theories using internal state variable (ISV) representations of damage have been used to predict the thermomechanical behavior of microcracked solids.

Damage variables and related effective stresses in continuum damage mechanics.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1988 A systematic theory to describe the anisotropic damage states of materials and a consistent definition of effective stress tensors are developed. By introducing a fictitious undamaged configuration mechanically equivalent to the real damaged configuration, the classical creep damage theory is extended to the general three-dimensional states of material

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Prediction of material damage in orthotropic metals for virtual structural testing [PDF]
, 2010 Models based on the Continuum Damage Mechanics principle are increasingly used for predicting the initiation and growth of damage in materials. The growing reliance on 3-D finite element (FE) virtual structural testing demands implementation and ...

Limit load capacity of compressed beam with imperfections [PDF]
Građevinski Materijali i Konstrukcije, 2018 This paper presents a theoretical investigation of elastic and inelastic buckling of thin-walled beam with initial imperfections. The main aim of this paper is to show that the fracture of beams varies from brittle to extremely ductile depending on the ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Meso-statistical damage constitutive model and validation of coal under CO2 - load coupling
Meitan xuebaoCO2 adsorption causes damage degradation to the coal body and thus reduces its stability, challenging the long-term safety of CO2 sequestration, and it is important to clarify the role of CO2 degradation and establish an ontological model.
