A three dimensional finite element modeling approach is used to evaluate the effects of preliminary design variables on the performance of tapered composite laminates under tensile loading. Hashin failure criteria combined with a progressive failure algorithm is used for in-plane failure mechanisms and cohesive zone method is used for out-of-plane failures. The modeling approach is validated by a comparison with experimental results from literature. The validated model is used to examine various design variables in terms of their effect on the ultimate tensile strength of the tapered laminate. Finite element models are created for several preliminary design variables and their effects are discussed.

Experimental and numerical failure analysis of advanced composite structures with holes Atar, Mehmet Bilal; Parnas, Kemal Levend; Department of Mechanical Engineering (2016) In this work, a design methodology for advanced composite structures with holes is presented. A three dimensional finite element model (FEM) is constructed to simulate such a structural application similar to weight-pockets in helicopter blades. Material properties are obtained by a material characterization study. The progressive failure method with FEM is used for the material degradation. In order to induce delamination in simulation, cohesive layers are implemented between composite layers. Results are ...
Failure analysis of thick composites Erdem, Melek Esra; Parnas, Kemal Levend; Department of Mechanical Engineering (2013) A three-dimensional finite element model is constructed to predict the failure of a hybrid and thick laminate containing bolted joints. The results of the simulation are compared with test results. The simulation comprises two main challenging steps. Firstly, for a realistic model, a 3D model is established with geometric nonlinearities and contact is takeninto account. The laminated composite model is constructed by 3D layered elements. The effect of different number of elements through the thickness is in...
Forced vibration analysis of generally laminated composite beams using domain boundary element method Ahmed, Zubair; Dağ, Serkan; Department of Mechanical Engineering (2018) Forced dynamic response of generally laminated composite beam is analyzed by boundary element method. Static fundamental solutions are used as weight functions in the weighted residual statements. The use of static fundamental solutions gives rise to a new formulation named as Domain Boundary Element Method. Displacement field of the generally laminated composite beam is written in accordance with first order shear deformation theory and equations of motion are derived using Hamilton’s principle. Developed ...
Thermal fracture analysis of orthotropic functionally graded materials using an equivalent domain integral approach Dağ, Serkan (2006-12-01) A new computational method based on the equivalent domain integral (EDI) is developed for mode I fracture analysis of orthotropic functionally graded materials (FGMs) subjected to thermal stresses. By using the constitutive relations of plane orthotropic thermoelasticity, generalized definition of the J-integral is converted to an equivalent domain integral to calculate the thermal stress intensity factor. In the formulation of the EDI approach, all the required thermomechanical properties are assumed to ha...
Nonlinear fiber modeling of steel-concrete partially composite beams with channel shear connectors Öztürk, Alper; Baran, Eray; Department of Civil Engineering (2017) The purpose of this study is to develop a nonlinear fiber-based finite element model of steel-concrete composite beams. The model was developed in OpenSees utilizing the available finite element formulations and the readily available uniaxial material constitutive relations. The model employed beam elements for the steel beam and the concrete slab, while zero-length connector elements were used for the steel-concrete interface. The channel shear connector response used in numerical models was based on the p...
