Application of Decoupled Scaled Boundary Finite Element Method to Solve Eigenvalue Helmholtz Problems (Research Note)

A novel element with arbitrary domain shape by using decoupled scaled boundary finite element (DSBFEM) is proposed for eigenvalue analysis of 2D vibrating rods with different boundary conditions. Within the proposed element scheme, the mode shapes of vibrating rods with variable boundary conditions are modelled and results are plotted. All possible conditions for the rods ends are incorporated ...

Application of the discrete element method to model cohesive materials

One way to include fracture and fragmentation when analyzing loaded mechanical systems is based on the DEM, [2], [3]. In recent years this approach was adopted in geomechanics and civil engineering to model fracture in elastic-brittle materials, e.g. [1] and [5]. Using this approach, the material is considered as being fully discontinuous and made up by assembling and bonding adjacent discrete ...

Explicit Finite Element Method Applied to Impact Biomechanics Problems

Biofidelic numerical models require accurate geometry, material properties, representative loading conditions, and proper verification and validation based on relevant experimental studies. Imaging techniques such as CT or MRI are typically used to generate anatomically correct model geometry. Accurate biological material properties and constitutive models present a challenge s...
