Freeze‐thaw cycle is a type of fatigue loading, and rock stress relaxation under freeze‐thaw cycles takes into account the influence damage deterioration. Rock one paramount issues in tunnel slope stability research. To accurately describe mechanical behaviour rocks freeze‐thaw, software element constructed based on theory fractional calculus to replace ideal viscous traditional model. The degradation viscosity coefficient considered. A new three‐element model established better reflect...
AbstractAbstractThe spreading behaviour of Cu97Si3 filler metal droplets under arc brazing is studied by finite element method (FEM) simulation using Surface Evolver software. The mathematical model pressure force acceleration added to the droplet microelement as form gravity used in numerical simulation. 3D profile for different welding currents then simulated. Finally, results were compared with experimental results, showing good correspondence. It was seen that height decreases and...
