The corresponding computational model for the application of the micromechanical approach to modeling of superelasticity in shape memory alloys is demonstrated. Material properties for No-Ti alloy (50,8 % Ni) obtained from literature and from our own experiments were applied to the model and a sample calculation of a 3D model subjected to uniaxial loading was performed. The results were compared to experimental results obtained from tensile and compressive tests.

A new method for digital curve length calculation based on the approximation with a B-spline has been introduced where the control points of a B-spline curve are the pixel center points. An approximate length of the digital curve is determined by calculating the length of the continuous B-spline curve. In the paper several examples are presented and the calculated lengths are compared to other methods found in the literature.

The aim of this is to identify the contact parameters between belt and pulley which can be used in a two-dimensional multi-body, belt-drive model. Two experimental setups are proposed in order to identify contact stiffness and friction coefficient between the V-ribbed belt and pulley. The friction coefficient is identified at various belt initial tensions and relative velocities between the belt and pulley. The measurement procedure and contact formulation is verified with numerical experiment.

The CWT methods have proven themselves to be resistant to noise and able to identify damping at closely spaced natural frequencies. Furthermore, the CWT is susceptible to the edge effect, which causes a non-valid identification at the start and end of the time-series. This study introduces a new method, called the Morlet-wave method, where a finite integral similar to the CWT is used for the identification of the viscous damping.

In this study the equations of a moderately thick plate are derived by the method of successive approximations. The derived equations exactly satisfy all the elastostatic equations, the plate equilibrium equations and traction free face boundary conditions.
