Linear peridynamics for isotropic and anisotropic materials

A non-ordinary peridynamics implementation for anisotropic materials

Peridynamics (PD) represents a new approach for modelling fracture mechanics, where a continuum domain is modelled through particles connected via physical bonds. This formulation allows us to model crack initiation, propagation, branching and coalescence without special assumptions. Up to date, anisotropic materials were modelled in the PD framework as different isotropic materials (for instan...

Laser picosecond acoustics in isotropic and anisotropic materials

We present experimental results concerning the laser generation of picosecond acoustic pulses and their propagation in isotropic and anisotropic materials. We make use of a conventional reflectance detection technique as well as interferometric detection to probe the real and imaginary changes in reflectance. We also demonstrate the detection of transverse acoustic waves by mode conversion at a...

A Theoretical Study of Wall Ironing for Anisotropic Workharden Materials

Modelling of the Magnetic Characteristics of Isotropic and Anisotropic Materials for Sensor Applications

The following paper presents the results of modelling of the magnetic characteristics of isotropic (Ni–Zn ferrite) and anisotropic material (Fe40Ni38Mo4B18 amorphous alloy in as quenched state), both useful for sensor applications. For the modelling an extended Jiles–Atherton model was used. Extension of the model connects model’s parameter k, describing average energy required to break pinning...

A unified multiaxial fatigue damage model for isotropic and anisotropic materials

A unified multiaxial fatigue damage model based on a characteristic plane approach is proposed in this paper, integrating both isotropic and anisotropic materials into one framework. Compared with most available critical plane-based models for multiaxial fatigue problem, the physical basis of the characteristic plane does not rely on the observations of the fatigue crack in the proposed model. ...
