Numerical Simulation of Reinforced Concrete Subjected to Multiaxial Stress Conditions
… a highly nonlinear behavior caused by cracking, crushing, aggregate interlock, bond slip, dowel action, shrinkage and creep. Because the reinforced concrete involves so many nonlinear phenomena interacting with one another, the formulation of a "complete" analytical model is very …

Non-linear Contact Analysis of Meshing Gears
… various potential faults such as misalignment, cracks, and noise. Therefore, it requires vibration monitoring to ensure the system is operating properly. Case mounted accelerometers are frequently used to monitor frequencies in a system. However, it is not a simple task to identify and interpret …

Modeling recycled aggregate concrete crack by extended finite element method and concrete damage plasiticity
… or pavements generally suffer from the crack problem. The morphology and growth process of cracks, most importantly, how these factors affect the concrete structure, is of great significance. The study of RAC is thus considerably needed to encourage the application of RAC. Crack modeling …

Vibration- and Impedance-based Structural Health Monitoring Applications and Thermal Effects
… detection of damage (in the form of a fatigue crack) in these specimen and to quantify the smallest detectable crack size in aluminum structures. This is done by applying the electrical impedance-based SHM method and using piezoceramic sensors and actuators. Moreover, in order to better extract …

Anisotrope Schädigungsmodellierung von Beton mit Adaptiver Bruchenergetischer Regularisierung
Der Gegenstand der vorliegenden Arbeit ist die Simulation von Betonstrukturen beliebiger Geometrie unter überwiegender Zugbelastung. Die Modellierung erfolgt auf Makroebene als Kontinuum und zur Lösung des mechanischen Feldproblems wird die Finite-Elemente-Methode verwendet. Ein neues …
