FE Analysis and Experimental Validation of Residual Stresses in Arc Welding
Abstract: This paper presents finite element analysis (FEA) of residual stresses developed in arc welded butt joints. Residual stresses attributed to welding pose significant problems in the accurate fabrication of structures because these stresses heavily induce brittle fracturing and degrade the buckling strength of welded structures. Therefore, estimating the magnitude and distribution of welding residual stresses and characterizing the effects of certain welding conditions on the residual stresses are deemed necessary.Keywords: …

Flow Simulation and Experimental Comparative Study of Aerodynamic Forces on NACA 2415 Airfoil Scaled Model
Abstract: Aerodynamic force, which would be brought upon by the relative motion of an object and the airflow, is the force that the air in which the body is submerged exerts on the body. The normal force resulting from force on the body's surface and the shear force resulting from airflow viscosity, also known as skin friction, are the two sources of aerodynamic force. Shear force is applied locally and parallel …
