This paper presents an investigation into the gust response and wing structure load alleviation of a 200-seater aircraft by employing a passive twist wingtip (PTWT).The research was divided into three stages.The first stage was the design and analysis of the baseline aircraft, including aerodynamic analysis, structural design using the finite eleme
Summary: Background: Though microvascular clamps are widely used for anastomosis training, there still have several shortcomings, including the bulging, expensiveness and unavailability due to sterilization.The aim of this study is to introduce a simple and novel microvascular training model without use of microvascular clamps.Methods: Femoral vess
Abstract The use of high strength aluminium alloys, such as 6XXX and 7XXX series, is continuously increasing for automotive applications in view of their good strength-to-weight ratio.Their formability at room temperature is limited and they are thus often formed at high temperatures to enable production of complex geometries.Critical challenges du
