Material transport by diffusion is present in nature, as well as in living organisms as a vital process. The basic and generally used is a phenomenologically established law, named Fick’s law, It states that the material flux is proportional to the concentration gradient and that the material flows from the higher to lower concentration. Howe...

Metastasis involves the dissemination of circulating tumor cells (CTCs) from the primary tumor, their survival in the bloodstream, and eventual colonization of distant organs. Adhesive interactions with platelets, leukocytes, and endothelial cells are critical to CTC survival and extravasation. Platelet adhesion enhances CTC viability and promotes ...

This review summarizes scientific findings from three European Commission FP7 projects. The first, ARTREAT (2008-2013), focused on a multi-level, patient-specific model of artery and atherogenesis for outcome prediction, treatment decision support, and virtual hands-on training. An original method for plaque formation and development was created an...

This paper contains two parts – the first is related to the mechanics of lung microstructure, and the second is a formulation of a multiscale-multiphysics model of the lung. The second part considers the entire lung that relies on the mechanics of the microstructure and recently developed a multiscale composite finite element of the lung tiss...

Finite element (FE) modeling the motion of deformable bodies within a fluid, as well as the interaction between the bodies, has been a continuous challenge over the years. There are in principle two approaches – loose and strong coupling between the FE models of the two domains, with their advantages and drawbacks. We here present our concept...

Understanding the biomechanical response of a femoral bone under physiological loads is critical for assessing bone health and fracture risk, particularly in aging populations affected by osteopenia and osteoporosis. This study investigates the mechanical behavior of the femoral bone under standing loading conditions across three bone states: healt...

This study investigates the drug release performance of electrospun composite nanofiber mats, which hold significant promise as drug carriers for site-specific delivery in therapeutic applications such as cancer therapy. Predicting drug release rates from poly(D,L-lactic-co-glycolic acid) (PLGA) nanofibers produced via emulsion electrospinning is c...

This paper presents a method for improving the numerical analysis of contact problems using a penalty formulation. Since contact phenomena are inherently nonlinear, particularly in the case of large deformations, an incremental solution strategy is required. Conventional Newton-Raphson algorithms often face convergence problems when many nodes make...

The concrete damaged plasticity (CDP) model is one of the most popular constitutive models implemented into various Finite Element Method software. The application to the real structures is documented in the literature, but still there are some doubts about the response in combination with the various finite elements. Simple benchmark examples simu...
