Bayesian calibration of coupled computational mechanics models under uncertainty based on interface deformation

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
Calibration or parameter identification is used with computational mechanics models related to observed data of the modeled process to find model parameters such that good similarity between model prediction and observation is achieved.

Mechanical computation in neurons [PDF]

open access: yesDevelopmental Neurobiology, 2009
AbstractGrowth cones are the main motile structures located at the tip of neurites and are composed of a lamellipodium from which thin filopodia emerge. In this article, we analyzed the kinetics and dynamics of growth cones with the aim to understand two major issues: first, the strategy used by filopodia and lamellipodia during their exploration and ...

A novel physics-based and data-supported microstructure model for part-scale simulation of laser powder bed fusion of Ti-6Al-4V

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2021
The elasto-plastic material behavior, material strength and failure modes of metals fabricated by additive manufacturing technologies are significantly determined by the underlying process-specific microstructure evolution.

Transient optical simulation by coupling elastic multibody systems, finite elements, and ray tracing

open access: yesJournal of the European Optical Society-Rapid Publications, 2023
Transient dynamical–thermoelastic–optical system simulation is an important expansion of classical ray tracing through rigid, resting lenses because the operating performance of high-precision optical systems can be influenced by dynamical excitations or

Bayesian Inversion with Open-Source Codes for Various One-Dimensional Model Problems in Computational Mechanics

open access: yesArchives of Computational Methods in Engineering, 2022
The complexity of many problems in computational mechanics calls for reliable programming codes and accurate simulation systems. Typically, simulation responses strongly depend on material and model parameters, where one distinguishes between backward ...

Numerical investigation of the basilar membrane vibration induced by the unsteady fluid flow in the human inner ear [PDF]

open access: yesArchive of Mechanical Engineering, 2020
For a deeper understanding of the inner ear dynamics, a Finite-Element model of the human cochlea is developed. To describe the unsteady, viscous creeping flow of the liquid, a pressure-displacement-based Finite-Element formulation is used.
