Failure Analysis of Laryngoscope Made of Acrylonitrile Butadiene Styrene.

The objective of this paper is to ascertain the failure analysis of laryngoscope made of ABS (Acrylonitrile Butadiene Styrene) material for application in laryngoscope. For failure analysis the von-mises stress distribution was investigated using commercially available software. For experimental validation and comparison ASTM standard specimens of two types of materials ABS and PLA (Poly lactic acid) material are fabricated and subjected to tensile testing in Electronic Tensometer a mini universal testing machine of capacity 2 KN. The 3D-CAD model of laryngoscope made of ABS materials is then used for the failure analysis for prediction and evaluation of its intended future application and commercialization.
