mechanical behaviour of Laminated Composite beam by the new multi layered Laminated Composite Structures model with transverse shear stress continuity
International Journal of Solids and Structures, 2003Co-Authors: Moussa Karama, K S Afaq, Sebastien MistouAbstract:Abstract This work presents a new multi-layer Laminated Composite Structure model to predict the mechanical behaviour of multi-layered Laminated Composite Structures. As a case study, the mechanical behaviour of Laminated Composite beam (90°/0°/0°/90°) is examined from both a static and dynamic point of view. The results are compared with the model “Sinus” and finite element method studied by Abou Harb. Results show that this new model is more precise than older ones as compared to the results by the finite element method (Abaqus). To introduce continuity on the interfaces of each layer, the kinematics defined by Ossadzow was used. The equilibrium equations and natural boundary conditions are derived by the principle of virtual power. To validate the new proposed model, different cases in bending, buckling and free vibration have been considered.

integration of active vibration control methods with finite element models of smart Laminated Composite Structures
Composite Structures, 2010Co-Authors: Levent MalgacaAbstract:Abstract Vibration control problems can be directly and systematically solved in a single analysis stage using commercial finite element programs. Integration of control methods into the finite element solutions (ICFES) can be achieved in ANSYS. In this work, first, the direct velocity feedback (DVF) control is tested on a 3-DOF mechanical system under a step input. The simulation results obtained by the ICFES are compared with the analytical results obtained by the Laplace transform method. Then, active control of free and forced vibrations in a smart Laminated Composite Structure (SLCS) with two different lay-ups is studied numerically and experimentally. The SLCS consists of a symmetric Laminated glass–epoxy Composite beam with [0/90]s and [45/−45]s lay-ups and a piezoelectric actuator. For the vibration suppression, the DVF control tested on a mechanical system is applied to the SLCS. In addition, displacement feedback (DF) control is studied. Experiments are conducted to verify the natural frequencies and the closed loop time responses. Analytical results for the mechanical system and experimental results for the SLCS match well to the corresponding results obtained using the ICFES technique.

Advanced material models for damage and failure analysis of fiber reinforced Composite Structures
2020Co-Authors: Rajaneesh A, Bruyneel Michaël, Ponthot Jean-philippeAbstract:Thin walled Composite Structures made of laminates with stacks of plies including continuous fibres (like UD or fabrics) are used in aircrafts, wind turbines, naval and automotive applications. In order to propose predictive finite element simulation tools that are necessary to speed-up the time to market of new products, it is important to use material models that can accurately represent different failure modes at the ply level of a Laminated Composite Structure. Additionally, damage at the ply interfaces, that is delamination, must also be taken into account in the model. Modelling progressive damage up to failure in Laminated Composite material is clearly a very difficult task
