Microcracking in Composite Laminates: Simulation of Crack-Induced Ultrasound Attenuation
Microcracking in composite laminates is a known precursor to the growth of inter-ply delaminations and larger scale damage. Microcracking can lead to the attenuation of ultrasonic waves due to the crack-induced scattering. 3D elastodynamic finite integration technique (EFIT) has been implemented to explore the scattering of ultrasonic waves due to microcracks in anisotropic composite laminates....
متن کاملMicro-crack ultrasound scattering in anisotropic composite laminates
A computational model of ultrasound scattering by micro-cracks in fiber reinforced polymer laminates is presented, foundational to study of micro-crack induced ultrasound attenuation. A model for transmission scattering response is developed using a boundary integral formulation, and associated approximate scattering theories are discussed. Numerical results are presented demonstrating applicat...

متن کاملDrug release rate and kinetic investigation of composite polymeric nanofibers
Objective(s): In this work, electrospun nanofibers were explored as drug delivery vehicles using tetracycline as a model drug. Nanocomposite fibers including chitosan (CS)/poly (ethylene oxide) (PEO) and antibiotic were successfully prepared using electrospinning. CS blended with PEO considering a weight ratio of (90/10), and then, nanofibrous samples were successfully e...
متن کاملExact and variational theorems for fracture mechanics of composites with residual stresses, traction-loaded cracks, and imperfect iInterfaces
By partitioning the total stresses in a damaged composite into either mechanical and residual stresses or into initial and perturbation stresses, it was possible to derive several exact results for the energy release rate due to crack growth. These general results automatically include the effects of residual stresses, traction-loaded cracks, and imperfect interfaces. The exact energy release r...
