Numerical Modelling of a Composite Sandwich Structure Having Non Metallic Honeycomb Core

This study focuses on combining precast concrete system and base isolation technique that could lead to a high-performance seismic resistance structural system. Some previous experimental results on precast concrete modules are presented and discussed. Principles and numerical implementation of base isolation technique are described and presented in details. Analysis of life cycle cost that compares the conventional system and a system that combines precast concrete system and base isolation technique shows promising results. The result from this study is a structural system that has high seismic performance and cost efficiency for certain class of structures and site conditions.

Fibre metal laminate (FMLs) are hybrid composite materials which consisted of metallic layers and fibre-reinforced polymer. Currently, FMLs are becoming increasingly utilized in a wide range of applications, such as aircraft, automotive, marine, sporting goods and medical due to their specific mechanical properties like superior impact resistance and fatigue resistance. ARALL (Aramid-Reinforced Aluminium Laminate), which is based on aramid fibres, GLARE (Glass Reinforced Aluminium Laminate), which is based on high-strength glass fibres and CARALL (Carbon Reinforced Aluminium Laminate), which is based on carbon fibres, are the most commercial products FMLs. This article analyzes pertinent literature associated with experimental work on FMLs and their constituent materials subjected to impact loading. It reviewed the mechanical properties, impact performance indices, crushing behavior, failure modes, and failure mechanisms of various FML structures with different variables (impact energy, fibre orientation, layup configuration, stacking sequence, metal arrangement, direction and type of reinforcement, laminate thickness, metal thickness) under impact conditions (lateral and axial impacts). Overall, the literature on the response of FML flat plate structures to axial impact loads is unreported, and the most current research focusing on the axial crushing of FML tubes. Hence, further studies are required to increase the applicability of FMLs in applications that may be impacted under axial loading.

The pollution of leather industry contains a wide variety of toxic substance. Many diseases are spread by these viruses, which enter the body through the mouth and nose. Leather industry waste that contains chrome is another sort of trash. Chrome Containing Leather Waste (CCLW) also generates various types of pollution. The study's response parameters are surface quality and energy consumption, while the machining parameters are cutting speed, feed rate, and depth of cut. The ideal set of machining settings, including those for minimal surface roughness and minimum energy consumption, have been determined using the response surface methodology (RSM). CCLW is used as primary reinforcement while for secondary reinforcement particle alumina has been utilized. Stir casting parameters were optimized using Response surface methodology (RSM), collagen was preheated at temperature 177.36°C, weight percent of collagen 1.43, stirring duration of stir casting is 180 s, alumina preheat temperature of 300°C and alumina weight percent of 5 has been determined to be best amalgamation of casting parameters. At optimal combination of characteristics, tensile strength of prepared composite was determined to be 162.45 MPa, composite tensile strength was increased by around 20.33 %.
