In this paper, free vibration, modal and stress state analyses of honeycomb sandwich structures with different boundary conditions was investigated major factors affecting the frequencies stiffness due to material or parameter changes were determined. The representative volume element (RVE) method used in work analytically numerically validated by comparing obtained results those available lite...

Applications of the optimal control problems arise in many fields of engineering and science. This talk presents a brief overview of the main ideas and concepts of optimal control problems. The discussion will take place in terms of the distributed parameter systems and on its applications to active control of smart mechanical systems and possible other applications will be introduced. The beha...

The work explores computationally the impact resistance of proposed bio-inspired sandwich beam comprising top and bottom carbon fiber reinforced polymer laminate skins sandwiching side-arched hot melt adhesive aluminum honeycomb dual-core, as by beak, skull bone, hyoid, spongy bone woodpecker head. Examined geometrical effects on behaviors include arched core thickness (3, 4.6, 10 mm) leg span ...

Abstract The equivalent parameters of hexagon aluminum honeycombs are work out with the theories sandwich plates in this paper. honeycomb plate reinforced by ring beam applied static load is simulated finite element model plates, which validated test. research results show that numerical calculation error less than 10% compared test results, acceptable for an engineering project, and mechanical...

Abstract In this study, the time-dependent mechanics of multilayered thick hyperelastic beams are investigated for first time using five different types shear deformation models modelling beam (i.e. Euler–Bernoulli, Timoshenko, third-order, trigonometric and exponential deformable models), together with von Kármán geometrical nonlinearity Mooney–Rivlin strain energy density. The laminated is as...
