Abstract:
Sound quality evaluation has turned into a standard idea in the structure in the field of vehicle acoustic performance optimization in an endeavor to determine the issue active noise control (ANC) techniques were created where auxiliary sources were proposed to lessen the noise inside the cabin. Therefore an endeavor has been made in this paper to audit the advancements so far did in the field of optimization thinks about on decrease of noise in the truck cabins by using acoustic materials. In light of this, it is to investigate the possibility of acoustic materials as aluminum and steel metals an option with plan to improve the cabin noise by NVH analysis can be carried out by using Ansys and Hypermesh software’s. By finding the analysis values of frequency, sound and weighted sound can be concluded the acoustic materials are good for quieter applications.

Abstract:
In the present work, an attempt is made to study the mechanical response of woven glass fabric/epoxy composite laminates using numerical modelling and experimentation. For this two different configurations namely double lap joined with single and double bolts are chosen. These laminates are subjected to numerical modelling using finite element analysis to study the joint strength and stress analysis. The joint strength of woven glass fabric composites is studied experimentally by conducting tensile test. Along with this the effect of varying edge distance to diameter ratios are studied both numerically and experimentally to arrive at safe design. Both numerical analysis and experimentally obtained bearing strength of composite laminated bolted joints are correlated. This is done in order to predict the the failure load and failure mechanisms in the composite laminate bolted joints. The variation in the numerically and experimentally obtained bearing strength values were well within 5% diference for both cases of single and double bolted joints.

Abstract:
The first principles investigation of structural, elastic, electronic and optical properties of cubic inverse Perovskite Sc3PbX (X= B, C) have been carried out by density functional theory (DFT). The calculated lattice parameters for both compounds are in good agreement with the available experimental data. The malleability indicator of materials, Paugh’s ductility index (G/B) is calculated which shows that Sc3PbB is ductile while Sc3PbC is brittle at ambient condition. The calculated total densities of states (TDOS) at Fermi level are 5.05 and 3.07 electrons/eV for Sc3PbB and Sc3PbC, respectively. It is obvious from band structure that Sc3PbB and Sc3PbC compounds are metallic in nature and 3d state of Sc is mainly responsible for this metallic behavior. Furthermore, the optical properties such as dielectric constants, refractive index, conductivity, extinction coefficient, loss function and reflectivity have studied and reported for radiation up to 25 eV for the first time for Sc3PbX (X=B, C). It is found that the reflectivity is about 84% for Sc3PbB and about 95% for Sc3PbC that occurs between 5 eV to 10 eV of incident radiation in the ultraviolet region.

Abstract:
Aluminum metal matrix composites with numerous reinforcements (hybrid MMCs) having enormous potentials of satisfying novel demands of progressive engineering applications due to their enhanced mechanical properties such as Brinell hardness, tensile strength and compressive strength. Bottom down Stir casting method is followed to produce aluminum as base metal and their reinforced with various reinforcement level 2,4and 6 % of Fe2o3 and graphite powder use in same fraction. The microstructure distinctive of composites were observed by focusing of inverted metallurgical microscope. In particular emphasis the results were compared in those three different reinforced fractions. Finally, the comparative observation of their composites and their performance improvement and its mechanical properties such as strength and hardness. It is found that there is a good improvement in ultimate tensile strength, hardness and compressive strength up to reinforcement fraction of Fe2o3 and graphite 4% in an aluminum metal matrix composite.

Abstract:
The main objects of this paper are to find out the effects of copper addition on porosity of eutectic Al-12 Si powder metallurgy alloy. This alloy is extensively used due to their unique properties in automobiles area such as pistons, rotary engine housings, liners etc. to reduce weight of the components and fuel consumption. In this experiment six Al-12Si-xCu alloys with copper content of 0.5%, 1.5%, 2.5%, 3.5%,4.5%,5.5% are produced. It is observed that the porosity of the sample increased with increase the copper content and also porosity is maximum in low compaction pressure.
