Bending analyses of isotropic, functionally graded, laminated composite, and sandwich beams are carried out using a quasi-3D polynomial shear and normal deformation theory. The most important feature of the proposed theory is that it considers the effects of transverse shear and transverse normal deformations. It accounts for parabolic variations in the strain/stress produced by transverse shea...

in this paper, a general solution for torsion of hollow cylinders made of functionally graded materials (fgm) was investigated. the problem was formulated in terms of prandtl’s stress and, in general, the shear stress and angle of twist were derived. variations in the material properties such as young’s modulus and poisson’s ratio might be arbitrary functions of the radial coordinate. various m...

The widespread use of adhesive bonded connections has been used in a range technical fields. In this paper, the interfacial stress distribution joint is presented. When determining whether or not structure dependable for operation, stresses that act along bond line an adhesively lap are utmost importance. purpose study to develop finite element solutions able anticipate shear and peel using the...

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

Three novel Bouligand inspired composites were produced by vacuum bag infusion manufacturing process and their quasi-static mechanical performance compared to a conventional aircraft laminate. A morphologic/physical study was first conducted for all configurations response under tensile, three-point bending (3-PB) interlaminar shear strength (ILSS) tests then evaluated discussed. No significant...
