In the present study, numerical analysis of concrete columns wrapped with different composite materials is conducted. Different fibre reinforced plastic sheets such as CFRP, BFRP, HFRP, AFRP, GFRP and steel wrapping are taken into consideration. A cylindrical specimen representing a short column modelled Total deformation, Directional deformation Equivalent stresses in core shell were obtained ...

The response of a neo-Hookean fiber composite undergoing finite out-of-plane shear deformation is examined. To this end an explicit close form solution for the out-of-plane shear response of a cylindrical composite element is introduced. We find that the overall response of the cylindrical composite element can be characterized by a fictitious homogeneous neo-Hookean material. Accordingly, this...

Effect of addition of filler material to the natural fiber composite was experimentally investigated. Composites are manufactured by the conventional hand-layup method. All composites are made with a fixed banana fiber with 15% weight fraction addition of different weight fraction of (0, 3, 5, 7.5%) groundnut shell ash is added to the composite. Tensile, hardness, impact and compressive strengt...

An accurate nonlinear hygrothermal-electro-elastic (HTEE) buckling analysis of piezoelectric fiber-reinforced composite cylindrical shells subjected to the coupled loading effects axial compression and hydrostatic pressure was established by considering nonuniform prebuckling effect. Nonlinear governing equations were derived based on higher-order shear deformation theory Novozhilov’s shell the...

Sonication technology has recently been touted to decrease composite viscosity during delivery and may allow better cavity preparation adaptation and minimize voids. The purpose of this investigation was to evaluate the difference between conventional, hand-placed, incremental application of a standard hybrid resin-based composite (RBC) and sonicated application of a bulk-fill RBC in box-type a...

The static buckling of a cylindrical shell of a four-lobed cross section of variable thickness subjected to non-uniform circumferentially compressive loads is investigated based on the thin-shell theory. Modal displacements of the shell can be described by trigonometric functions, and Fourier’s approach is used to separate the variables. The governing equations of the shell are reduced to eight...
