TL;DR: In this article, the main objective of this project is to analyze bird strike on the aircraft jet engine Fan blade, the analysis is done and an attempt is made to discuss Deformation, Stress, and Strain on the Fan Blade depending on the Relative Velocity.
Abstract: Bird strike otherwise called as avian ingestion is the collision between the bird and the aircraft. It is a very dangerous situation in the field of aviation. Bird strike usually occurs at low altitude during take-off and landing of the aircraft. The bird strike in the jet engine is very dangerous because when a bird hits the fan blade the fan blade is displaced into other fan blade causing the cascading failure. The main objective of this project is to analyze bird strike on the aircraft jet engine Fan blade. Hemispherical Model is used to design the Bird Model. The Canadian goose and GE-NX 2B engine Fan Blade is taken to perform the analysis. The Calculation of the dimensions of the bird model is done. The fan Blade and Bird Model is designed and then assembled using CATIA V5R20. The material Properties is defined for both Bird Model and Fan Blade. The analysis is done and an attempt is made to discuss Deformation, Stress, and Strain on the Fan Blade depending on the Relative Velocity. ANSYS- Explicit Dynamics was used to analyze the Model.

TL;DR: This paper presents techniques to combat the unique DSP-related challenges of Explicit Dynamic data and then demonstrates them on a very challenging transient problem of a steel ball impacting a plastic LCD display in a portable phone, correlating simulation and experimental results.
Abstract: Explicit Dynamic Finite Element techniques are increasingly used for simulating impact events of personal electronic devices such as portable phones and laptop computers. Unfortunately, the elastically-dominated impact behavior of these devices greatly increases the tendency of Explicit Dynamic methods to calculate noisy solutions containing high-frequency ringing, especially for acceleration and contact-force data. For numerous reasons, transient FEA results are often improperly recorded by the analyst, causing corruption by aliasing. If aliasing is avoided, other sources of distortion can still occur. For example, filtering or decimating Explicit Dynamic data typically requires extremely small normalized cutoff frequencies that can cause significant numerical problems for common DSP programs such as MATLAB. This paper presents techniques to combat the unique DSP-related challenges of Explicit Dynamic data and then demonstrates them on a very challenging transient problem of a steel ball impacting a plastic LCD display in a portable phone, correlating simulation and experimental results.

TL;DR: In this article, the authors investigate the construction of the fan blade and eventually strengthen its' resistance to bird strikes, which is a cause of worry in the aeronautical industry: aircraft both old and new have suffered from bird strikes.
Abstract: Bird strike, also known as avian ingestion, is the collision between a bird and an aircraft. Bird strikes have always been a cause of worry in the aeronautical industry: Aircraft both old and new have suffered from bird strikes. Jet engine ingestion occurs when the bird hits the jet engine of an aircraft and gets sucked in. Given that the fan blades rotate at a high rpm, bird strike on a fan blade causes its displacement into the adjacent blade. This leads to a cascading failure, wherein the entire system fails, thereby resulting in a lot of damage. In this article, we intend to investigate the construction of the fan blade and eventually strengthen its' resistance to bird strikes.

TL;DR: In this article, the authors examine the relationship between Islamic notions of work and management and there relevance in the context of business management and present an attempt to examine the relation between Islam and business management.
Abstract: Religion has a major impact on human behavior, social interactions, and social relations. One can argue that laws and regulations are enough to induce ethical and moral decision making. But just like having a police force doesn't alleviate crime. Having business regulations do not ensure that businesses will conduct their affairs ethically. Regulatory drivers alone are not sufficient to safeguard public interest from the ill affect of greed and unethical corporate behavior. The focus of Islamic way of business is not just to earn profit but to serve the society. The human welfare is the gist of Islamic business ethics. The present paper is an attempt to examine the relationship between Islamic notions of work and management and there relevance in the context of business management.

TL;DR: In this paper, a collision model of height limit protection frame of railway bridges and the over-high vehicles using the software of ANSYS/LS-DYNA and studying the dynamic response of protection frame impact loading by the vehicle under different parameters.
Abstract: Height limit protection frame of railway bridges apply to the road crossing the railway bridge, its role is to ensure the safety of the railway bridge to prevent road motor vehicles to hit the bridge beam, causing beam damage and even endangering the safety of the railway lines. Therefore, it is necessary to do in-depth discussion of collision mechanism and failure mode of height limit protection frame of railway bridges under the impact of the over-high vehicle, in order to improve the survivability of protection frame to protect the safety of the railway bridge and rail transport. Some rules and characteristics were obtained by establishing collision model of height limit protection frame of railway bridges and the over-high vehicles using the software of ANSYS/LS-DYNA and studying the dynamic response of protection frame impact loading by the vehicle under the different parameters. Thus for the similar protection frame structure design, maintenance and damage assessment provide theoretical support.
