ABSTRACT Constraint can be divided into two conditions of in‐plane and out‐of‐plane, each them has its own parameter to characterize. However, in most cases, there exists a compound change both out‐of‐plane constraint structures, unified measure that reflect is needed. In this paper, the finite element method (FEM) was used calculate equivalent plastic strain ( ɛ p ) distribution ahead crack tips for specimens with different constraints, FEM simulations based on Gurson–Tvergaard–Needleman...
ABSTRACT In this paper, the specimens with different geometries and loading configurations were used to study unified correlation of in‐plane out‐of‐plane constraints fracture toughness by using numerical simulation method. The results show that constraint parameter A p which was defined on basis areas surrounded equivalent plastic strain isolines ahead crack tip can characterise both induced specimen configurations. sole linear relation between normalised J IC /J ref obtained. ‐ line is a...
Abstract The synergistic strategy of nanozyme‐based catalytic therapy and photothermal holds great potential for combating bacterial infection. However, challenges such as single limited enzyme property, unfavorable environment, ineffective interaction between nanozymes bacteria, unsafe laser irradiation ranges, failed trauma fluid management impede their antibacterial capability wound healing speed. Herein, the first time, a PNMn hydrogel is fabricated with multi‐enzyme activities excellent...
Recently, the Ruddlesden-Popper bilayer nickelate La3Ni2O7 has been discovered as a high temperature superconductor with Tc near 80 K above 14 GPa.[1-3] The search for superconductors higher Tc, preparation of high-quality single crystals, and removal high-pressure conditions including crystal growth under gas pressure achievement superconductivity pressure, are most challenging tasks. Here, we present ambient flux crystals up to 91 pressure. Single La3-xRxNi2O7-y dimensions 220 um on edge...
To realize imaging-guided multi-modality cancer therapy with minimal side effects remains highly challenging. We devised a bioinspired hollow nitrogen-doped carbon sphere anchored individually dispersed Mn atoms (Mn/N-HCN) via oxidation polymerization triton micelle as soft template, followed by carbonization and annealing. Enzyme kinetic analysis optical properties were performed to evaluate the photothermally synergized nanocatalytic therapy. Simultaneously mimicking several natural...
Based on the numerical simulation method of virtual crack closure technique (VCCT), an interference model was established to investigate physical problem two interacting cracks different sizes in welding zone oil and gas pipelines. The obtained results current were compared with those single case. Various configurations, such as spacing sizes, analyzed. characteristic quantity fluid pressure load P during propagation process, peak value von Mises stress distribution field growth path, well...
For the sake of realizing safety detection natural gas and petroleum pipeline welds, this paper designs a ferromagnetic weld magnetic flux leakage detector based on calculation circuit probe, with magnetization direction perpendicular to traveling direction. The traditional device uses system mode in which is parallel travel. However, due structural characteristics weld, not applicable. Since needs travel along designed rotates magnetizer 90 degrees seam so that travel, breaking through...
A fast local neighbourhood search (FLNS) algorithm is proposed in this paper to minimise the total flow time no-wait shop scheduling problem, which known be NP-hard for more than two machines. In work, an unscheduled job sequence constructed firstly according processing and standard deviation of jobs on This undergone initial optimisation using basic algorithm. Then, innovative scheme designed partial each iterative calculate solution with objective increment method. not only improves...
In pipelines for transporting oil and gas, multiple cracks often exist in weld joints. The interaction among the should be considered as it directly affects life span of pipeline structures. current investigation, based on fluid–solid magnetic coupling model, virtual crack-closure technique (VCCT) is applied to systematically study multi-crack dynamic effect welds during crack propagation process. results show that existence an auxiliary accelerates main crack’s propagation. When nearer tip,...
Wafer processing is the most expensive, time-consuming, and complex stage in semiconductor manufacturing. It varies significantly based on orders of customers (agents). Optimising wafer flow a multi-agent scenario can meet customised requirements, speed up delivery, reduce costs. This work models as job shop scheduling problem (MAJSP) with release dates. The objective to minimise total weighted makespan agents. To address both dynamic static scenarios MAJSP context, two deep reinforcement...
