Abstract null null Static and free vibration analysis of simply supported FGM sandwich shells is presented in this paper using a new higher order shear and normal deformation theory. The higher order theory developed herein considers the effects of transverse normal stresses. The theory uses higher order variations of in-plane as well as transverse displacements. Hamilton’s principle is used to formulate the equations of motion. Solutions of simply supported cylindrical and spherical shells are ...

Abstract null null A systematic multi-disciplinary design approach to the optimum tailoring of composite materials is a challenging design optimization problem. It involves the tailoring of null composite material properties null null as per the design requirements. While designing any component, typical cost or weight reduction involves the use of optimization together with corresponding analysis. Depending upon various performance requirements, different types of analyses become the design dri...

Abstract null null null For practical null fiber reinforced plastic null (FRP) structures, fibers are randomly packed in matrix, and some degree of clustering is often observed because of imperfect control of manufacturing process. In this work, a new method to generate random fiber distribution including fiber clustering is proposed according to fiber clustering characteristics of typical micro-image of FRP cross section. Irregularity and nearest neighbor fiber characteristics of random fiber d...

Abstract null null Laminated safety glass is popularly used as facades and structural elements in buildings. For safety concerns, the bonding between glass and interlayer needs to be ensured. Pummel test is one of the most commonly used approaches to evaluate the interfacial adhesion of laminated glass. This paper is concerned with the development of a software-based pummel-value evaluation method. First, a series of pummel tests were conducted to characterise the adhesion capacities of various ...

Abstract null null The problem of central impact of composites has been analysed in-depth, but the damage caused by near-edge and on-edge impact has not been thoroughly discussed. In this paper, three-dimensional hashin failure criterion based on stress description is used to judge the damage of fiber and matrix, and delamination damage is simulated by zero thickness cohesive element. In order to characterize the stiffness degradation of damaged composites, the improved Camanho nonlinear reducti...

Abstract null null The present work investigates the thermo-protective ablative and dynamic mechanical properties of two kinds of epoxy resins modified with carbon nanotubes (1 vol.% or 5 vol.% of CNT) and homogenized mechanically or ultrasonically. The samples have been subjected to combustion gases at a temperature above 1900°C during 120 s. The best thermal protective properties were exhibited by the composites made by epoxy resin called Epidian 52 (cross-linked by TFF - triethylenetetramine)...

Abstract null null A procedure for the calculation of multiaxial laminates made out of unidirectional, continuous fiber-reinforced polyamid-6 (CF-PA6) is shown in this paper. The aim is to use the VDI 2014-3 guideline ( Puck null ’s theory) for the calculation of null thermoplastic composites null and to validate the quality of the calculation results with experimental tests. First, the CF-PA6 material properties are determined by different mechanical tests on cylindrical specimens. These are th...

Abstract null null In contrast to all the previous researches, a 3D transformation model is used here instead of the less accurate 1D models for the energy dissipation/pseudoelasticity response evaluation of the shape memory alloy (SMA) wire-reinforced-composite plates in the microscale world, for the first time. The governing equations are developed by incorporation of the modified strain gradient theory (MSGT) in the principle of minimum total potential energy. The governing equations are exte...

Abstract null null In this paper, the influence of salt fog and ambient condition exposure on CFRP-to-steel bonded joints (CSJs) with a near end mechanical anchorage was studied. The tests of the CSJs were carried out with a monotonic loading history respectively with and without a near end mechanical anchorage both unaged and after being exposed to the ageing conditions. The results revealed failures in the adhesive for some CSJs with a near end mechanical anchorage, among which also exhibited ...

Abstract null null null null null A novel hybrid composite structure is proposed, which can shield null electromagnetic pollution null and substantially increase null null sound absorption null at the same time. The structure can be prepared using a facile manufacturing method. The theoretical model, FEM simulation, and experimental results indicate that the hybrid composite structure has an null null electromagnetic shielding null null efficiency of more than 90 dB in the X band. In addition, t...
