The finite element method (FEM) is probably the most-used simulation technique in engineering. Modern finite-element software makes doing FE simulations easy – too easy, perhaps. Since you have a nice graphical user interface that guides you through the process of creating, solving, and postprocessing a finite element…

Modeling of physical systems includes extensive use of software packages that implement the accurate finite element method for solving differential equations considered along with the appropriate initial and boundary conditions. When the problem size becomes large, time needed to solve the resulting linear systems may…

Finite element analysis of complex bodies is frequently used in design to determine the size of deformations. Successive iterations, with progressive refinement of mesh densities, are most often required to obtain a sufficiently accurate convergent numerical solution. This process is costly, time consuming, and…

Mechanical properties of an aneurysmatic thoracic aorta are potential markers of future growth and remodeling and can help to estimate risk of rupture. Aortic geometries obtained from routine medical imaging do not display wall stress distribution and mechanical properties. Mechanical properties for a given vessel may…

Constitutive modeling is the cornerstone of computational and structural mechanics. In a finite element analysis, the constitutive model is encoded in the material subroutine, a function that maps local strains onto stresses. This function is called within every finite element, at each integration point, within every…

Bio ceramics have enormous applications in the medical field as being used as implants. The base material in bioceramics is mostly calcium phosphate which comes in the form of hydroxyapatite (HAp) or Beta-tricalcium phosphate (β-TCP). The other materials are silica and alumina. The different blends of these bioceramics…

Finite element models are frequently used to simulate traumatic brain injuries. However, current models are unable to capture the progressive damage caused by repeated head trauma. In this work, we propose a method for computing the history-dependent mechanical damage of axonal fiber bundle tracts in the brain. Through…
