摘要:Abstract(#br)A novel method coupling the scaled boundary finite element method (SBFEM) and the finite element method (FEM) is developed for linear elastic fracture modelling. A very simple but effective remeshing procedure based on the FE mesh only is used to accommodate crack pr...

摘要:Abstract(#br)We take the single-crystalline (La 1− x Sr x ) 2 CuO 4 system ( x = 0.068) as an example to study flux dynamics in the mixed state of high- T c superconductors by systematically measuring its c -axis resistivity, ϱ c , as a function of temperature, magnetic-fiel...

摘要:Abstract(#br)A procedure for generating two-dimensional heterogeneous meso-scale concrete samples is developed, in which the multi-phasic features including the shape, size, volume fraction and spatial distribution of aggregates and pores are randomised. Zero-thickness cohes...

摘要:Abstract(#br)The influence on the magnetohydrodynamic (MHD) behaviors due to the gas injected by Super-sonic Molecular Beam Injection (SMBI) has been observed on J-TEXT tokamak. The change of local electron temperature and density due to the injected supersonic gas triggers relax...
