A Bayesian Framework for the Calibration of Cyclic Triaxial Tests

Geotechnics
This research presents the calibration of a constitutive model to replicate the cyclic performance of soils using a Bayesian framework. This study uses data from laboratory-conducted consolidated undrained isotropic cyclic triaxial tests and numerical ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

Study on Key Controlling Factors of Fracture Propagation by Shaped Charge Blasting in Coal Seams

Energy Science &Engineering, EarlyView.
Gas drainage is the fundamental approach to controlling gas disasters in coal mines. For single low‐permeability coal seams, it should be supplemented by coal seam permeability enhancement technologies to improve gas drainage efficiency. This paper conducted a numerical simulation study on the key controlling factors affecting the fracturing effect of ...

Cyclic Loading and Fabric Evolution in Sand: A Constitutive Investigation [PDF]

, 2015
An anisotropic plasticity model is proposed to describe the effect of fabric and fabric evolution on the cyclic behaviour of sand within the framework of anisotropic critical state theory.
