The present study shows that the state-space concept used to generate exact solutions for various boundary conditions for bending, buckling and free vibration of composite laminates, can be modified easily and exactly and has no drawback when the laminate thickness is reduced. Numerical results for central deflections, axial stresses, transverse shear stresses, critical buckling loads and natural frequencies of cross-ply laminated plates are obtained using the classical, first- and third-order theories for large side to thickness ratios.

A COMPARISON OF THE THERMAL PERFORMANCE OF A CONVENTIONAL FIN BLOCK AND PARTIALLY COPPER AND ALUMINUM FOAM EMBEDDED HEAT SINKS Ataer, S. Kaancan; Yamali, Cemil; Albayrak, Kahraman (2020-01-01) In this research, the metal foams with 4,8,16 pores/cm, an aluminium foam which has 0.93 porosity and a copper foam which has 0.90 porosity that are integrated into a heat sink with a special geometry were designed and tested. During the process of the experiments, the thermal resistances and the pressure losses of the metal foam integrated heat sinks were tested by applying different heat fluxes (10.67, 15.75, 21.33 and 31.50 kW/m(2)) and two distinct frontal air velocities (4 and 6 m/s) to the specimens. ...
Inelastic seismic response of precast concrete frames with constructed plastic hinges Sucuoğlu, Haluk (1995-07-01) A modified seismic design concept is introduced for precast concrete frames in which beam plastic hinges with reduced yield capacities are constructed away from the precast beam-column connections arranged at the column faces. Plastic hinge location and yield capacity are employed as the basic parameters of an analytical survey in which the inelastic dynamic responses of a conventional precast frame and its modified counterparts are calculated and compared under two earthquake excitations by using a general...
Application of the H-N method to the critical slab problem for reflecting boundary conditions Tureci, RG; Gulecyuz, MC; Kaskas, A; Tezcan, C (Elsevier BV, 2004-11-01) The recently developed H-N method is used to solve the critical slab problem for a slab which is surrounded by a reflector. In the special case: for R = 0 (the reflection coefficient) the problem reduces to the one under vacuum boundary conditions. It is shown that the method is concise and leads to fast converging numerical results. The presented numerical results are compared with the data available in literature.
An investigation on compatibility properties of exterior finish coats for insulated walls in terms of water vapour pemeability and modulus ofelasticity Örs, Kerime; Tavukçuoğlu, Ayşe; Department of Building Science in Architecture (2006) The compatibility properties of some contemporary finish coats together with their complementary layers used in insulated exterior walls were examined in terms of water vapour permeability and modulus of elasticity. Basic physical and mechanical properties of some synthetic-, cement- and polymer-based external finish coats were analyzed in laboratory. Some additional samples, complementing the wall section, were also examined for their water vapour permeability. Results showed that the finish coats were hig...
Investigation of effect of design and operating parameters on acoustophoretic particle separation via 3D device-level simulations Sahin, Mehmet Akif; ÇETİN, BARBAROS; Özer, Mehmet Bülent (Springer Science and Business Media LLC, 2019-12-16) In the present study, a 3D device-level numerical model is implemented via finite element method to assess the effects of design and operating parameters on the separation performance of a microscale acoustofluidic device. Elastodynamic equations together with electromechanical coupling at the piezoelectric actuators for the stress field within the solid parts, Helmholtz equation for the acoustic field within fluid, and Navier-Stokes equations for the fluid flow are coupled for the simulations. Once the zer...
