Based on the lower bound theorem of limit analysis, a solution procedure for limit analysis of three-dimensional elastoplastic structures was established using
By using the extended homogeneous balance method, the localized coherentstructures are studied. A nonlinear transformation was first established, and then theli
The steady oil production and pressure distribution formulae of vertically fractured well for power-law non-Newtonian fluid were derived on the basis of the ell
The finite strip method in structural analysis has been extended, and elasticplastic large deformation spline finite strip method based on the Updated- Lagrange
