in this paper coupled nonlinear equations of motion of a suspended cable with time dependent tension and velocity are derived by using hamilton’s principal. a modal analysis for a stationary sagged cable is initially carried out in order to identify the dynamic system. the natural solution is directed to compute the natural frequencies and mode shapes of the free vibration of a suspended cable....

In this paper,we investigate the pricing and return policy issueof one-echelon green supply chain, contain a manufacture who produces two type of products: green and non-green products. These products have a same functional but in selling price and environmentally issues have different effects. Also we consider return policy for both products that can stimulate the customer valuation. We develo...

Results from a combined experimental and numerical investigation into the effects of rate on mode-II fracture of a plastically-deforming, adhesively-bonded joint are presented. It is shown that a cohesive-zone model has to be modified to include coupling between normal and shear modes of deformation when there is extensive shear deformation of the adhesive layer. A suitable cohesive-zone modeli...

fracture of mixed mode i/ii in beech wood and its wood polymers has been investigated experimentally in this study. hence, two crack systems of tl and rl were selected in which the crack planes extend along the wood fibers. this investigation has demonstrated that onset of mixed mode cracking can be predicted with a very simple fracture criterion in these crack systems. results indicated that f...

For optimization of real-world arch dams, it is unavoidable to consider two or more conflicting objectives. This paper employs two multi-objective differential evolution algorithms (MoDE) in combination of a parallel working MATLAB-APDL code to obtain a set of Pareto solutions for optimal shape of arch dams. Full dam-reservoir interaction subjected to seismic loading is considered. A benchmark ...

Motivated by the inadequacy of conducting atomistic simulations crack propagation using static boundary conditions that do not reflect movement tip, we extend Sinclair's flexible condition algorithm [J. E. Sinclair, Philos. Mag. 31, 647 (1975)] and propose a numerical-continuation-enhanced scheme, enabling full solution paths for cracks to be computed with pseudo-arclength continuation, present...
