Combining the advantages of basalt fiber-reinforced polymer (BFRP) material and steel material, a novel BFRP-steel composite plate (BSP) is proposed, where a steel plate is sandwiched between two outer BFRP laminates. The main purpose of this research is to investigate the mechanical behavior of the proposed BSP under uniaxial tension and cyclic tension. Four groups of BSP specimens with four d...

Abstract The perforation resistance of fibre metal laminates (FMLs) made an S-glass reinforced poly-ether-ketone-ketone (GF/PEKK) composite and aluminium alloy (2024-T3) is investigated. Initial attention focused on assessing the effect processing temperature tensile strength alloy. Here, it has shown that cycle results in a reduction approximately 35% both yield A comparison quasi-static dynam...

Controllable bending stiffness and damping has significant applications in soft robotics, especially for soft slender manipulator arms inspired by octopus tentacles. The bending moment on a solid slender beam is balanced by the sum of moments generated by internal stresses. Resulting stresses are not controllable and decided by the bending curvature, area moment of inertia and elastic modulus o...

This paper studies the efficiency of applying an engineered cementitious composite (ECC) layer to tensile surface (RC) beams that were previously strengthened using externally bonded (EB) carbon fiber-reinforced polymer (CFRP) laminates. One control and ten RC produced tested utilizing a four-point loading regime. For beams, two kept only CFRP, additional ECC layers added rest beams. The CFRP w...

Fiber-metal laminates (FMLs) offer the superior characteristics of polymer composites (i.e., light weight, high strength and stiffness) with ductility fracture metals. The bond between two dissimilar materials, composite metal, dictates properties performance FMLs. bonding becomes more critical when matrix is thermoplastic hydrophobic in nature. This work employed a novel technique metal layer ...

Aircraft wings are designed with very low factor of safety to keep the aircraft weight minimum. Thus, for safe design wings, stress analysis should be carried out under accurately estimated aerodynamic loads and this can achieved only through coupled fluid-structure analysis. Moreover, modern made laminated composite structures thus purpose study is employ ANSYS find best layup wing an that res...

This work examines the influence of kerosene flame exposure on residual mechanical behavior (tension and compression) hybrid quasi-isotropic composite laminates consisting carbon/glass fibers a PEEK thermoplastic matrix. The (116 kW/m2 1100 °C), composites structural integrity was examined as function time (5–10-15 min). changes in tensile compressive properties (axial stiffness strength) were ...

Thin-ply composites are gaining significant attention owing to their high damage resistance and ability enhance design flexibility in a composite structure. Herein we proposed mechanics model considering diffuse discrete ply damages thin-ply laminates for mesoscale simulation. To investigate the effects of thickness on evolution, loading unloading tests were conducted using cross-ply, angle-ply...

(Abstract) Genetic algorithms are well known for being expensive optimization tools, especially if the cost for the analysis of each individual design is high. In the past few years, significant effort has been put forth in addressing the high computational cost GAs. The research conducted in the first part of this thesis continues this effort by implementing new multiple elitist and variable e...
