A finite element approximation is proposed for the dynamic analysis of two-dimensional (2D) lattice materials. The unit cell is modeled by means of a defined number of shear deformable micro-beams. The main innovative feature concerns the presence of a microstructure-dependent scale length, which allows the consideration of the so called size-effect that(More)
The static behavior of reinforced concrete (RC) beams plated with layers of fiber-reinforced composite material (FRP) is widely investigated in current literature, which deals with both its numerical modeling as well as experiments. Scientific interest in this topic is explained by the increasing widespread use of composite materials in retrofitting(More)
PURPOSES The aim of the study was to assess by means a 3D finite element linear and non-linear analysis mechanical interaction between an implant-supported crown and surrounding tissues. MATERIALS AND METHODS A three-dimensional FEM model was developed. Four different material combinations for the abutment and the core were evaluated: Y-TZP - Y-TZP, Y-TZP(More)

In this paper a numerical investigation relative to the static behaviour of thin-walled beams of open cross-section, undergoing moderate angles of twist, is presented. The constitutive equations between nominal stresses and Green strains are assumed to be linear elastic and isotropic. The numerical results are obtained by using a finite element approach,(More)
