Evaluation of J-Integral and Fatigue Crack Growth Rate of Semi-elliptical Crack in Compressor Blade
Abstract: Gas turbine compressor blades are subjected to centrifugal, gas bending and vibratory loads. This repeated loading and unloading can reduce the life of compressor blades. This research aims at the estimation of fatigue crack growth rate of various three-dimensional cracks in a compressor blade considering the J-integral calculations for a semi-elliptical crack, subjected to centrifugal loading. Static stress analysis was carried out to ascertain the critical region or crack zone …

Operational Modelling and Analytical Analysis of Connecting Rod Using the Computer Aided Design
Abstract: The main objective of this study was to explore weight reduction opportunities for a production forged steel connecting rod. This has entailed performing a detailed load analysis. Therefore, this study has dealt with two subjects, first, static load stress analysis of the connecting rod, and second, optimization for weight. In this project, finite element analysis of single cylinder four stroke petrol engine is taken as a case study. Structural systems …

Design Optimization of A Riveted Joint Used in Back Plate of A Pendulum Absorber Assembly
Abstract: Riveted joints are widely used for fastening sheet metal components. Cylindrical rivets are generally preferred but due to space constraints in some cases, other geometries are being explored. In this work, a practical case of a rectangular riveted assembly for back plate of pendulum absorber assembly commonly used in modern vehicles for damping secondary vibrations is considered and an iterative simulation study for design optimization has been conducted using finite …

Fabrication of Air Conditioning Suit
Abstract: A PPE kit is personal protective equipment. PPE (Personal Protective Equipment) is specific clothes or equipment worn by employees to assure themselves against infectious materials. By forming a barricade between the potential infectious material and the health care worker, PPE avoids contact with an infectious agent or body fluid that may contain an infectious agent. An air conditioning is done by using an Ac machine which produce a cooling effect …

Numerical Investigation of Missile Strike over an Unmanned Aerial Vehicle
Abstract: Objectives: The present work deals with the impact analysis of missile over an unmanned aerial vehicle (UAV), the missile is made to strike on the UAV with various angles on the different locations and structural behaviour of the UAV will be investigated through the intended work. Novelty: There is very limited data concerning structural failure modes caused by impact and explosion loading on an UAV due to missiles. Method: The …

An Exact Kolmogorov–Smirnov Test for the Negative Binomial Distribution with Unknown Probability of Success
Abstract: AbstractIn this paper, we develop an exact Kolmogorov–Smirnov goodness-of-fit test in the case of negative binomial distribution with an unknown probability of success. This test is conditional, with the test statistic being the maximum absolute difference between the empirical distribution function and its conditional expectation given the sample total. The results are not asymptotic, but exact. We illustrate the test with three examples in case the size parameter equals one …

An Exact Kolmogorov–Smirnov Test for the Logarithmic Series Distribution with Unknown Parameter
Abstract: AbstractIn this paper, we develop an exact Kolmogorov–Smirnov goodness-of-fit test in the case of logarithmic series distribution with an unknown parameter value. This test is conditional, with the test statistic being the maximum absolute difference between the empirical distribution function and its conditional expectation given the sample total. Some modifications are done on an algorithm previously proposed in the case of the Poisson distribution and used the modified algorithm for …
