The present work formulates the dynamics of a slender structure as a long beam. This results in a PDE that is fourth-order in space, and second order in time. In COMSOL the coupling method is used to decompose this problem into two second-order equations, one for displacements, and one for bending moments, which are then solved to obtain frequencies and mode shapes. For verification of ...

A hyperelastic seal is pulled over a metal ring in a coffee machine for maintenance reasons. The force needed to pull the hyper elastic seal over the part is too high and should be reduced for maintenance reasons. Using the COMSOL Multiphysics® Structural Mechanics Module, and using the non-linear hyperelastic for the stick slip movement, a reliable simulation was generated. It resulted in an ...

The geometrical design and material choice for a refractory lining requires a good understanding of its thermo-mechanical behavior. Design engineers clearly need a tool for fast and efficient computation of thermo-mechanical state of refractory linings under various conditions. However, standard simulation models and their solutions suffer as the linings are composed of many refractory blocks in ...

The dynamic behavior of cable supported bridges subjected to moving loads and affected by corrosion and accidental failure mechanism in the cable suspension system is investigated. The different types of cable supported bridges are distinctively characterized by the configuration of the cable system . The suspension system comprises a parabolic main cable and vertical hanger cables connecting ...

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium fuel are ongoing at ORNL as part of an effort sponsored by the U.S. Global Threat Reduction Initiative program. HFIR is a very high flux, pressurized light-water-cooled and moderated, flux-trap type research reactor whose current missions are to ...

The tensile strength of masonry is relatively low compared to its compressive strength and is affected by the direction of the joints and their filling. In masonry with modern thin layer mortar (joint thickness 3 to 5 mm) sometimes the head joints are left open. A total of 13 model-walls was built and for each model four general purpose mortar combinations and three thin layer mortar ...

Electromigration induced failure is one of the main reliability issues for the microelectronics industry. The continuous scaling of the interconnect dimensions leads to higher operating current densities and temperatures, which accentuates the electromigration failure. As a consequence, electromigration still poses challenges for the development of the new technological nodes. Electromigration ...

The primary function of the vestibular system is to provide the brain with information about the body\'s motion and orientation. The absence of this information causes blurred vision and spatial disorientation, vertigo, dizziness, imbalance, nausea, vomiting, and other symptoms often characterize dysfunction of the vestibular system. Our aim is to design vestibular prosthesis using COMSOL ...

In this study, COMSOL Multiphysics® software was used to simulate the surface response to excitation method (SuRE). An aluminum beam with a piezoelectric element bonded is modeled using the COMSOL Acoustics Module. A frequency domain sweep study was performed to simulate the sweep sign generation. The frequency spectrum of the structure is monitored through a frequency range of (20kHz-400kHz). A ...
