In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...

analysis and prediction of structural response to static or dynamic loading requires prediction of concrete response tovariable load histories. the constitutive equations for the mechanical behavior of concrete capable of seeing damage effects or crack growth procedure under loading/unloading/reloading was developed upon micro-plane framework. the proposed damage formulation has been built on t...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

body's iterative force-field computer program has been used to calculate strain energies in cyclooctanone (i). 348 mhz 1h nmr spectra of (i) have been investigated over the temperature range of 25° to -160°c. two conformation processes affect the 1h nmr spectrum of (i). iterative force-field calculations on the conformations and conformational interconversion paths of (i) give results consisten...

The phase-field microelasticity theory has exhibited great capacities in studying elasticity and its effects on microstructure evolution due to various structural and chemical non-uniformities (impurities and defects) in solids. However, the usually adopted linear and/ or collinear coupling between eigen transformation strain tensors and order parameters in phase-field microelasticity have excl...

Abstract. In this work, a novel multiscale model for softening periodic microstructures is proposed, relying on nonlinear homogenization method combined with cohesive/volumetric finite element model. This strategy able to overcome the mesh sensitivity issues usually experienced by purely volumetric techniques in presence of strain localization. As main ingredient proposed approach, microscopica...
