1. 1. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

   University essay from KTH/Matematik (Avd.)

   Author : Bill Claesson; [2023]
   Keywords : ;

   Abstract : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. READ MORE

3. 2. Efficient FE Modeling of Large Casted Parts

   University essay from KTH/Maskinkonstruktion

   Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
   Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

   Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

4. 3. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

   University essay from KTH/Hållfasthetslära

   Author : Abhiroop Chatterjee; [2023]
   Keywords : ;

   Abstract : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. READ MORE
