“…Strength is to measure the potential and hold against the braking when the load is applied to the materials. The buckling stability increased comparison to straightforward epoxy composite [4]. Greater value acting as an outcome of the particle's homogeneous distribution, which limits their capacity for plastic deformation [16,29].…”

<p>The wastes are in many forms consist of organic materials like human, medical, food, plastics, construction waste etc. many researchers are focused on the waste management to gives more importance to the environment. The bio degradable waste was used in this research with naturals fibers. The need for hybrid composites has increased in a variety of industrial applications. A unique and useful substance is created when two or more distinct components join in this kind of composite. Because of its exceptional characteristics, research is being done on the integration of particles bio waste and fiber into polymers. The like a strong weight-to-strength ratio, immunity to rust and temperature changes, and several custom qualities. This research focuses on the property description of Calotropis Gigantea and Bio waste ashes in form of epoxy matrix and in concrete as retrofitting composite. Calotropis Gigantea and Bio waste ashes are in composite form. field emission scanning electron microscope (FESEM) The characterisation is used to make sure that the polymer's structural shape and particle dispersion are correct. The mechanical, dynamic mechanical, thermal wear and concrete strength qualities are assessed. When particles are added, the qualities improve. By raising the weight of particle at certain percentage to the matrix and concrete mixture is for to increase the mechanical properties like tension, elongation, impact. To analyze the tribological behaviour, wear analysis is carried out. The results revealed that, the laminates reinforced with Calotropis Gigantea and Bio waste ashes show maximum strength. This is correlated with the increased interaction between the fiber-matrix, waste ash and homogeneous dispersion particle and also having greater strength compare to conventional concrete. The FESEM micrographs for tensile fracture surface also provided structural morphology. The findings will provide a vivid understanding for the use of composites in various structural retrofitting applications.</p>

“…Analysis of the results of atomic force microscopy (AFM) and high‐resolution transmission electron microscopy (HRTEM) in their study showed that the appropriate dispersion of nanofillers has improved the nanocomposites' properties. Rubber Composites (poly‐ethylene propylene diene monomer rubber [EPDM]/SBR/nanoclay rubber) reinforced with 2.5‐phr, 5‐phr, 7.5‐phr, and 10‐ phr nanoclay (Cloisite 15A) were synthesized and evaluated by Ravi Theja et al [ 26 ] on a two‐roll mill with a vulcanizing agent (sulfur). Curing properties showed that nanoclay not only accelerates the crosslinking process but also results in a significant increase in torque, which indicates that the synthesized composites' crosslinking density increases with the presence of nanoclay.…”

This paper deals with the fatigue life analysis of a blend of natural rubber (NR) and styrene‐butadiene rubber (SBR) with and without nanoclay particles. Various damage parameters based on strain are investigated. A nonlinear finite element analysis is carried out by using ABAQUS. To formulate the life prediction models, the measured fatigue life is used together with various damage parameters. It is shown that all the damage parameters can estimate the fatigue lives effectively with correlation coefficients greater than 0.9. There is a good agreement between the obtained fatigue live predictions and the measured fatigue results. The effect of various parameters such as true strain and nanoparticles' loading is also investigated. The results of sensitivity analysis show that the strain has a greater effect on the variation of the rubber compounds' fatigue life. The test samples' fracture surface is assessed via scanning electron microscopy (SEM). SEM results show that as the strain increases, the test samples softly fail while the fracture surface of the nanocomposite is roughened by the addition of nanoclay.

“…Multicell square columns compressed axially using analytical and numerical techniques [24]. In hexagonal honeycombs and circular honeycombs, the influence of the central angle and the boundary effect is found to be an important factor in the crushing strength of the structure when the number of cells is very small [25,26]. Analysis was carried out to develop the crashworthiness of thin-walled sections, and the circular honeycombs with the square package and hexagonal package were examined numerically and experimentally [27,28].…”

This paper aims to identify the optimum level of factors or parameters that affect the energy absorption of conoidal structures by grey relational examination. To optimize crashworthiness parameters of conical structures, the L9 orthogonal array has been adopted to design the experiments. The tailor-made thin-walled conical structures were fabricated by three most important factors, such as base diameter, height, and thickness, as design variables, and they were subjected to axial compression in a quasi-static method. The important responses of crashworthiness indicators such as the mean crushing force and specific energy absorption (SEA) were calculated with the help of a load-displacement curve. Experimental results showed that the crushing behaviours of conical structures were fairly significant. Grey relational analysis (GRA) and analysis of variance are used toobtain the optimal levels of parameters. From the results, the optimum levels of parameters are found to be a base diameter of 180 mm, a height of 120 mm, and a thickness of 1.5 mm.
