Dr. Marcos Valdebenito delivers a plenary lecture at VibSys 2024
The 31st Conference Vibrations in Physical and Technical Systems (VIBSYS 2024) was hosted by Poznan University of Technology. The event took place from October 16th to October 18th in Poznan, Poland. Dr. Marcos Valdebenito from the Chair for Reliability Engineering represented the Chair and delivered a plenary lecture.
VIBSYS is a periodically organized scientific event with a 60-year-old tradition. It gathers scientists working in the field mechanical vibrations. The thematic scope of the conference includes, among others, dynamics of machinery, vibroacoustics, waves in solids and liquids, stability and control issues as well as biomechanics.
Dr. Marcos Valdebenito’s plenary lecture, entitled "Advanced Simulation Methods for Analysis and Design in Stochastic Linear Dynamics", addressed a key challenge in the analysis of structural systems subjected to dynamic stochastic loads such as wind, waves, or earthquakes. These forces are inherently uncertain and time-dependent, requiring advanced modeling techniques to assess the likelihood of structural responses exceeding critical thresholds – a probability known as the first excursion probability.
In his talk, Dr. Valdebenito showcased how modern simulation methods can tackle the complexity of these high-dimensional, highly correlated problems. He emphasized the importance of understanding how structural property changes influence reliability under stochastic loading, as well as strategies for optimizing designs to withstand such conditions. Additionally, he addressed epistemic uncertainties, which arise from limited knowledge or incomplete data, highlighting the need for robust approaches to ensure reliable structural performance.
By blending theoretical concepts with practical case studies, Dr. Valdebenito demonstrated the significant potential of these tools for advancing both the analysis and design of engineering systems.
