Fast and Accurate Simulation of Manufactured Parts with Defects

Published 2019-05-01 by Tech Briefs Media Group in United States

Unwanted porosity is typical to many manufacturing processes — from traditional casting to additive manufacturing (3D printing) — and is difficult to avoid entirely. Manufacturers need to know what amount of porosity is tolerable inside a part without affecting its strength and performance.

Fatigue Tests of Un-Notched and Notched Specimens and Life Prediction Using a Variable Critical Distance Method

General Motors-Neeraj Carpenter, Pankaj Jha, Sudipto Ray, Michael D. Nienhuis
Published 2019-04-02 by SAE International in United States
Fatigue is one of the most common failure mechanism in engineering structures. The statistical nature of fatigue life and the stress gradient are the two challenges among many while designing any component or structure for fatigue. Fatigue lives of the identical components exhibit the considerable variation under the same loading and operating conditions due to the difference in the material micro-structures and other uncontrolled parameters. Stress concentration at the notch causes stress gradient and therefore, applying the plane specimen results for actual engineering components with notches does not give quantitatively reliable results if the stress gradient effects are not considered. The objective of the work presented here was to carry out the fatigue tests of un-notched, U and V-notch specimens which were die cast using aluminum alloy (A380) and to obtain fatigue life using a variable critical distance method which considers the stress gradient due to the notch geometry. Specimens were prepared in the foundry shop in a way to minimize the microstructural variations and a radiography study was carried out to ensure that cast…

Experimental Studies on Mechanical Properties of Metal Matrix Composites Reinforced with Natural Fibres Ashes

Delhi Technological University-Ravi Butola, Aahan Malhotra, Mukesh Yadav, Ranganath Singari, Qasim Murtaza, Prakash Chandra
Published 2019-04-02 by SAE International in United States
Metal matrix composites have a large range of applications in the automobile industry due to its characteristics and properties. Al-based MMC have aluminum as matrix metal that has properties which are well concerned with the automobile industry. Some of these properties are high strength to weight ratio and lightweight. In this paper we are trying to develop aluminum-based metal matrix composite (MMC) reinforced with natural fibers ashes, we are using fine ashes of Sugarcane (bagasse), Groundnut Shell Ash (GSA), Rice Husk Ash (RHA) and Coconut shell (Jute) ash, different effects are investigated for different percentage of reinforcing material which is being produced by burning in a free atmosphere. Ball milling is used for making fine particle size of different natural fibers ash. Nine samples were made by the stir casting process consisting of Al6063 as base metal and different concentration of reinforcement. Maximum UTS was recorded for the specimen having composition 4% each reinforcement and balance aluminum 84%. Maximum yield Strength was found for the specimen having Coconut (jute) ash 4% and balance aluminum 96%.…
