Critical expansion points: Mechanical signs of surrounding rock instability

open access: yesDeep Underground Science and Engineering, EarlyView.
This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

Aseismic Capability of Beam-to-Column Joint in RC Frame Under Biaxial Loading

open access: yesAdvances in Civil Engineering
The aseismic capability of a beam-to-column connection may be lower under identical bidirectional compared to unidirectional loads. However, earthquake excitations are multidimensional and random, so joints may be simultaneously subjected to different ...

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

open access: yesDeep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

open access: yesEcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Cruciform specimens used for determination of the influence of T-stress on fatigue crack growth with overloads on aluminum alloy Al 6061 T651

open access: yesFracture and Structural Integrity, 2019
The publication presents a cruciform specimen for the determination of cyclic crack growth data under biaxial loading. The design of the specimen with slotted loading arms allows good decoupling between the two loading directions.

Planar biaxial testing of CXL strengthening effects

open access: yesExperimental Eye Research
The stiffening effect of corneal crosslinking (CXL) treatment, a therapeutic approach for managing the progression of keratoconus, has been primarily investigated using uniaxial tensile experiments. However, this testing technique has several drawbacks and is unable to measure the mechanical response of cornea under a multiaxial loading state.

Strain and Band Modulation of WO3/SnSe Micro‐Nano Composites Achieving Superior Photocatalytic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
WO3/SnSe micro‐nano composites demonstrate exceptional photocatalytic performance through synergistic strain and band modulation. Lattice strain modulation enhances methyl orange adsorption and visible light absorption, while Z‐scheme band alignment promotes efficient charge separation. The 2.5% WO3/SnSe composite achieves 99.71% degradation efficiency,

Manufacturing and testing of a cruciform coupon for biaxial transverse tests

open access: yes, 2022
The present study deals with the manufacturing of cruciform coupons to be tested under tensile biaxial transverse loads. The objective is to obtain a geometry that minimizes the effect of stress concentrations, maximizes the area subjected to biaxial loads and uniforms it, and assures failure occurrence in this area.

Linear‐Nonlinear‐Linear Sandwich‐Structured Polymer Composites With Metal‐Organic Framework (MOF)‐Enhanced Insulating Layers and Horizontally Oriented Nanotube‐Filled Polarization Layer for High Energy Storage Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A linear‐nonlinear‐linear (LNL) sandwich dielectric film was rationally designed for high energy storage. Its outer linear layers are MOF (ZIF‐8)‐enhanced PEI composites (EZ), and the middle nonlinear layer is an electrospun‐hot‐pressed P(VDF‐HFP)/TNTs composite (PT) with horizontally oriented TNTs.
