“…Role of SMA on vibration parameters was studied analytically by [10,11] and [12]. Natural frequencies of SMA embedded composite beams were studied using various beam theories and considering axial load generated by the recovery action of pre-strained SMA wires by [13], including the optimization and machine learning based studies of the shift in the natural frequency of a nitinol-reinforced composite beam has recently been discussed [14,15]. The application of SMA with shape memory effect for embedding into composite was observed in improving the natural frequency and damping characteristic of GFRP and CFRP (Carbon-fiber-reinforced polymers) composite based hollow shafts [16].…”

The shape memory eﬀect (SME) is a source of internal compressive stresses that modify the vibration behavior of shape memory alloy (SMA) embedded composite structures. Generally, long ﬁbers are used due to their suitability for activating SMA using resistive heating. Longer SMA ﬁbers embedded in composite structures have their limitations in design and manufacturing. Minimal research work has been done on tuning the vibration behavior of composite structures embedded with short SMA ﬁbers. In this research paper, an analytical model for evaluating the natural frequencies of an SMA embedded composite beam has been proposed. Eﬀects of various design parameters for long (continuous) and short (discontinuous) SMA ﬁbers embedded in composites have been investigated. It was observed that short SMA ﬁbers with a higher aspect ratio can tune their frequencies similarly to long SMA ﬁber composites and are more eﬀective in thicker beams. Matrix material with negative coeﬃcient thermal expansion is more suitable for embedding SMA for modifying natural frequency in active mode.

Owing to the superior qualities, aluminum metal matrix composites (AMMC) have recently been accepted and suggested as a replacement for traditional materials in a variety of sectors, including automotive, agriculture, aerospace, sports, marine, and many more. To satisfy the industrial requirement, it is necessary to develop economical material with higher mechanical properties like strength, hardness, impact resistance etc. To minimise the environmental impact and depletion of natural resources , it is necessary to Reduce, Recycle and Resuse the solid waste created across the world. This work aims to study the mechanical behavior of hybrid composite of Al6061 reinforced with coconut shell ash (CSA) and granite dust solid waste. Hybrid composite specimens were successfully manufactured using stir casting method. The proportion of granite dust was kept constant at 2 wt. percent, whereas the percentage of CSA varied, ranging from 0% to 12% with a multiple of 3. Tests for tension, compression, hardness, and impact were performed to examine the mechanical behavior of the created hybrid composites. SEM & EDAX analysis were carried out to study the microstructure and elemental composition of the hybrid composites. Experimental testing shows that, when the percentage of CSA in the hybrid composite increased, its tensile strength, compressive strength, hardness, and impact strength increased maximum up to 23.65%, 10.12%, 60.89% and 17.38% respectively as compared to base alloy. The experimental findings demonstrated that when compared to matrix and other hybrid composites, the Al6061 alloy reinforced with 2% granite dust and 12% CSA hybrid composite had superior mechanical properties.
