Developing a unified theory to describe granular matter, which can behave like either solid or fluid, is one of the grand challenges in modern science. This mainly because current theories, rooted different origins, interpret matter from disparate perspectives and are hard merge. In this work, we demonstrate that it possible generate such generic by bridging elastoplastic solids with rheological law flow. The proposed mathematical model well explain avalanching behaviours occurring...
Optimizing the joint drawdown operation of mega reservoirs presents a significant opportunity to enhance comprehensive benefits among hydropower output, water release, and carbon emission reduction. However, achieving complementary while considering reservoir emissions poses notable challenge. In this context, study introduces an innovative multi-objective optimization framework tailored for reservoirs. Firstly, model, leveraging intelligent evolutionary algorithm, is developed minimize...
A hierarchical structure poly-particle swarm optimization (HSPPSO) approach using the concept of control theory is presented. In bottom layer, parallel calculation performed on swarms, which enlarges particle searching domain. top each swam in layer treated as a single swarm. The best position found by regard result fed back to layer. If some particles trend local extremum (PSO) algorithm implementation, velocity updated and re-initialized. test proposed method four typical functions shows...
Hydrodynamic and elastoplastic theories are two commonly used continuum approaches for modeling granular materials. Here, the approach is extended to incorporate rheology of dense flow, which therefore allows a quantitative comparison with hydrodynamic under same setting rheological laws, material parameters, numerical method. The flow patterns yielded by apparently similar discharge rates close. Yet creates narrow dome‐like zone in contrast wide cone‐like generated approach. shear...
Reservoir impoundment operation has far-reaching effects on the synergies of hydropower output, floodwater utilization, and carbon fluxes, but flood risk is significantly increasing, which especially true when shifting to earlier timings lifting reservoir water levels. This study proposed a novel framework driven by prevention, production, emission management. The Three Gorges in Yangtze River was selected as case study. results demonstrated that prevention safety could be guaranteed with...
To deal with distribution network reconfiguration, a hierarchical structure poly-particle swarm optimization (HSPPSO) approach using the concept of control theory is presented. In bottom layer, parallel calculation performed on swarms. top each particle swam in layer treated as particle. The best position found by regarded single swarm. result fed back to layer. Considering features network, probability producing feasible solutions improved modifying rule updating. test proposed method two...
Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of midrise or high-rise structures. This study mainly focuses on structural damage evaluation type timber–steel structure that incorporates prefabricated light wood-frame shear walls into steel moment-resisting frames (SMRFs). The such was evaluated through shake table tests 4-story large-scale structure. Four ground motion records (i.e., Wenchuan...
The analytical theory and computational method for thin-walled curved box girders in terms of the shear lag effect geometric nonlinearity are presented. Based on potential variational principle girders, geometry nonlinear governing differential equations girder considering influence flange’s stress large deflection is established. equation solved by means Newton-Raphon iteration method. results from present good agreement with those test segment numerical examples conducted to verify...
Multilayer membranes prepared via microlayer coextrusion have attracted wide attention due to their unique properties and broad applications. In present study, the foam/film alternating multilayer sheets based on ethylene-vinyl acetate copolymer (EVA) high-density polyethylene are successfully coextrusion.
