Experimental and numerical investigation of damage process in composite laminates under low-velocity impact
Topaç, Ömer Tanay; Çöker, Demirkan; Gürses, Ercan; Department of Aerospace Engineering (2016)
Damage sensitivity of composites under out-of-plane dynamic loading, and its limited detectability on a structure has long remained a prominent problem in industry. In this study, simulations are compared with the real-time damage formation scheme, with the aim of increasing confidence in failure predictions. Drop-weight impact experiments are carried out on a [0/90]_s CFRP beam laminate. Initiation and progression of damage, consisting of matrix cracks and delamination, are visualized via ultra-high-speed ...
Theoretical and experimental investigation on characteristics of adsorption cooling systems using advanced porous materials
Bonyadi, Nima; Yamalı, Cemil; Baker, Derek Keıth; Department of Mechanical Engineering (2014)
The solid sorption cooling systems are getting more popular around the globe due to their benign behavior and possibility to work with renewable energy. Despite many advantages, the overall efficiency of adsorption cooling systems is still low in comparison to vapor compression chillers. Researchers declare that heat and mass transfer and adsorption capacity inside the adsorbent bed have dominant role on the performance of the cooling unit. One way to increase both adsorption capacity and heat distribution ...

A boundary element formulation for axi-symmetric problems in poro-elasticity
Özyazıcıoğlu, Mehmet H; Özkan, M. Yener; Department of Civil Engineering (2006)
A formulation is proposed for the boundary element analysis of poro-elastic media with axi-symmetric geometry. The boundary integral equation is reduced to a set of line integral equations in the generating plane for each of the Fourier coefficients, through complex Fourier series expansion of boundary quantities in circumferential direction. The method is implemented into a computer program, where the fundamental solutions are integrated by Gaussian Quadrature along the generator, while Fast Fourier Transf...
Theoretical and experimental investigation of ultrasound propagation in packed beds
Karakaş, Zeynep; Uludağ, Yusuf; Department of Chemical Engineering (2016)
Ultrasound propagation through porous medium is investigated theoretically and experimentally in this study. Allowing measurements with opaque medium, giving fast measurements, requiring low cost and being non-invasive make the use of ultrasound based techniques convenient. Propagation of sound is directly related to the physical properties of a porous medium such as porosity, bulk modulus of medium, density of medium, particle size and physical properties of sound such as frequency. Therefore, it becomes p...
