Civil Engineering
My original profession is civil engineering, with a special interest in numerical modeling and stability. I graduated from Budapest University of Technology and Economics (BME).
Flexural buckling of thin-walled lipped channel columns with slotted webs: Numerical and analytical studies
The research analyzes the flexural buckling of thin-walled steel columns with slotted webs. A constrained finite element method was used to isolate key influencing factors, revealing that in-plane shear deformations significantly impact buckling behavior.
An analytical model was developed to estimate critical loads, considering shear effects, stiffness reduction due to slots, and second-order strain terms. Extensive numerical studies confirmed the accuracy of the model and demonstrated its practical applicability in structural engineering.
Experiments and numerical models for eigenfrequency identification of fluids
Structural reliability depends on accurately determining loads and effects, but challenges arise when the relationship between action and effect is highly nonlinear. A key example is resonance, where periodic forces near a structure’s natural frequency can amplify its response significantly.
This study examines a water tower model, comparing analytical predictions with laboratory experiments and Smoothed Particle Hydrodynamics (SPH) simulations. The focus is on refining numerical methods to capture the effects of fluid movement more precisely.
By improving post-processing techniques and enhancing simulation accuracy, the research provides deeper insights into fluid-structure interactions, helping engineers design safer and more resilient structures.
