This study concentrates on FEA modelling of concrete beam strengthened with externally bondedCFRP lates under bending by using Traction Separation Law (TSL) as constitutive law to require maximum cohesive stress and fracture energy values. The models were developed following experimental work reported Al-Rousan et al. [23] Ding [22]. Combination two numerical techniques adopted, i.e., Extended ...

We provide an analytical formulation to model the propagation of elastic waves in a homogeneous half-space supporting array thin plates. The technique provides displacement field obtained from interaction between incident wave generated by harmonic source and scattered fields induced flexural motion each plate is calculated using ad-hoc set Green’s functions. modelled through multiple scatterin...

Article history: Received 19 May 2010 Received in revised form 15 September 2010 Accepted 5 October 2010 Available online 13 October 2010 Flexural waves are scattered by inclusions in a thin plate. For a single inclusion of arbitrary shape, reciprocity relations are obtained connecting coefficients in circular multipole expansions. Then, a formula for the effective wavenumber in a random arrang...

The free flexural vibration of a stiffened rectangular plate is investigated by using the finite element method (FEM). In the present model, the plate can have arbitrary elastic boundary conditions and arbitrarily located stiffeners. Numerical studies are conducted to analyze the natural frequencies of concentrically/eccentrically stiffened plates with different boundary conditions and the resu...
