Abstract Conventional material processing approaches often achieve strengthening of materials at the cost reduced ductility. Here, we show that high-pressure and high-temperature (HPHT) treatment can help overcome strength-ductility trade-off in structural materials. We report an initially strong-yet-brittle eutectic high entropy alloy simultaneously doubling its strength to 1150 MPa tensile ductility 36% after HPHT treatment. Such synergy is attributed HPHT-induced formation a...
Abstract The crack initiation stress threshold ( $${\sigma }_{\mathrm{ci}}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mi>σ</mml:mi> <mml:mi>ci</mml:mi> </mml:msub> </mml:math> ) is an essential parameter in the brittle failure process of rocks. In this paper, a volumetric strain response method (VSRM) proposed to determine based on two new concepts, i.e., dilatancy resistance state index $${\delta <mml:mi>δ</mml:mi> and maximum value difference...
Abstract This paper investigates the mechanical properties and permeability of chemically corroded rock during deep underground tunneling. Nuclear magnetic resonance tests are carried out to quantify chemical damage limestone samples at microscopic scale. Coupled hydrostatic pressure-unloading different unloading rates also conducted on these investigate changes effects behaviours. Magnetic imaging, T 2 spectrum distribution porosity obtained, micro is visualized quantified. The relationship...
The question "How does it work" has motivated many scientists. Through the study of natural phenomena and behaviors, intelligence algorithms have been proposed to solve various optimization problems. This paper aims offer an informative guide for researchers who are interested in tackling problems with algorithms. First, a special neural network was comprehensively discussed, called zeroing (ZNN). It is especially intended solving time-varying problems, including origin, basic principles,...
The ability to generate complex and realistic human body animations at scale, while following specific artistic constraints, has been a fundamental goal for the game animation industry decades. Popular techniques include key-framing, physics-based simulation, database methods via motion graphs. Recently, generators based on deep learning have introduced. Although these models can automatically highly intricate stylized motions of arbitrary length, they still lack user control. To this end,...
Rock strength is imperative for the design and stability analysis of engineering structures. The Mohr-Coulomb (M-C) criterion holds significant prominence in geotechnical engineering. However, M-C fails to accurately capture nonlinear response neglects critical state rocks, potentially leading inaccuracies phase deep projects. This study introduces an innovative stress-dependent friction angle cohesion (SFC) responses intact spanning from non-critical states (brittle ductile regions). A...
The research on the fragmentation mechanism of seabed minerals under high ambient pressure significantly contributes to exploitation seafloor massive sulfides (SMS). In this paper, uniaxial compressive strength (UCS) test and triaxial (TCS) were carried out two kinds SMS samples obtain key mechanical properties minerals, including cohesion, internal friction angle, strength, elastic modulus. Then, based these parameters, fluid-solid coupling cutting model at is established by using method...
This study utilises NaOH to treat composite cementitious materials containing aeolian sand and zeolite powders, which were used replace 50% of the cement in aeolian-sand concrete (ASC). The mechanical properties treated ASC considerably improved, especially when dosage was 4% by mass. After curing this sample (denoted as AAZC-4) for 28 d, its compressive strength improved 17.2% split tensile increased 16.3%. Potassium feldspar montmorillonite powder SiO2 decomposed OH− combined with other...
This paper mainly reports the experimental research on damage detection of large generator stator insulation using theory elastic guided waves.

Efficiently retrieving an enormous chemical library to design targeted molecules is crucial for accelerating drug discovery, organic chemistry, and optoelectronic materials. Despite the emergence of generative models produce novel drug-like molecules, in a more realistic scenario, complexity functional groups (e.g., pyrene, acenaphthylene, bridged-ring systems) extensive molecular scaffolds remain challenging obstacles generation complex organics. Traditionally, former demands extra learning...
