Professor Martin Ostoja-Starzewski delivered the opening plenary lecture at the jointly organized ECCOMAS Thematic Conferences COMPDYN 2025 and UNCECOMP 2025, held earlier this month in Rhodes, Greece.
This was the 10th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN) and the 6th International Conference on Uncertainty Quantification in Computational Science and Engineering (UNCECOMP).
Ostoja-Starzewski’s lecture, “Tensor Random Fields for Stochastic Mechanics,” discussed his research motivated by the fact that deterministic continuum mechanics models tackled by boundary value problems may be insufficient in various engineering and natural systems, especially in multiscale problems. Viewed from the standpoint of random microstructures, probabilistic models such as stochastic partial differential equations (SPDEs) and stochastic finite elements (SFEs) should naturally include tensor-valued random fields (TRFs) with generally anisotropic realizations on mesoscales and nontrivial correlation functions.
The lecture extended his previous work on scalar RFs (including random processes) in vibration problems, bars and beams with random properties under random loads, elastodynamics, wavefronts, fracture, homogenization and contact mechanics.
The conference focused on the increasing necessity to solve complex problems in structural dynamics and earthquake engineering, which require the development of new ideas and innovative advanced computational methods and software tools.
