In this paper, concrete specimens with type I prefabricated cracks were prepared, and three-point bending tests used to investigate the influence of parameters, such as carbon fiber reinforced polymer (CFRP) plate thickness, depth crack, strength, loading speed, on bonding performance structures externally attached CFRP plates. The CCD cameras observation system, digital speckle technology is a...

In this paper, the flexural response of functionally graded plates with porosities is investigated using a novel higher order shear deformation theory, which considers the influence of thickness stretching. This theory fulfills the nullity conditions at the top and bottom of the plate for the transverse shear stresses, thus avoids the need of a shear correction factor. The effective material pr...
