“…With the advancement of computing technology, numerical approaches are much favourable, particularly within a finite element modelling (FEM) framework (Wang et al, 2015). In earlier work, due to singularity stress occurred at the notch tip, FEM requires very fine mesh at the vicinity of the notch and further increases difficulties to model a sharp crack.…”

The aim of the current project is to carry out the FEA framework for predicting the flexural strength of notched foam concrete tested under three-point bending following the conducted experimental set-up. The investigated testing series have a variation of notch size opening in the foamed concrete beam. The Tractionseparation relationship was used as a constitutive model to incorporate independent material properties and used in the modelling framework. Modelling techniques of 2D XFEM and CZM were adopted and later expanded to 3D XFEM models. Good agreement was found between the predicted structure response and experimental observation for all the investigated models. Crack was initiated at the crack tip and propagated to the beam edge under the applied load. It was found that the average discrepancies below 20% were found within XFEM techniques. Less agreement was found using the CZM models, partly due to the simplification of the adopted failure path. The modelling framework implemented in this project is potentially used as a predictive tool in estimating the flexural strength of the concrete beam with notches.

Considering the increased importance of robots nowadays, when no large factory or factory can work without robots, we want to present in the work the motion equations of the machine in an original form, both in terms of aspect and their deduction. The machine's motion equations can be used in dynamic calculations at any type of machine, whether it be a motor, a compressor, a lucrative machine, a robot, a system, a mechanism, a vehicle, a mechanical transmission, or any other type of car. The dynamics of systems is their real movement, the dynamic movement, in which the influences of three main factors interfere, which modify the kinematics of the mechanism when it moves really, dynamic. The first dynamic factor is the forces of inertia or the effect of inertial masses. The second important dynamic factor is that of the couplings, of the linkages within the respective machine mechanisms. The latter and the third dynamic factor represents the influence of system elasticity on its dynamic functioning. Only dynamic coefficient of inertia and the influence of kinematic couplings in the system were used in the analyzed sample. The dynamic coefficient due to elasticity and deformation in the system has not been taken into account since the overwhelming influence of the inertial forces is impacted by additional dynamic changes and also by the kinematic couplings in the system and the elastic deformations do not greatly influence the dynamics of the system in the case of the example remembered. If a robot was being discussed, things were similar, as in the case of various vehicles and various mechanisms and machines. However, for rigid memory transmissions, elastic deformations are important, which is why they should be considered in such systems.

With the evolution of technology, the construction and geometry of the piston, together with the materials from which it is made, as well as the related manufacturing technologies, have been continuously improved. Thus, modern engines have become less polluting, working at higher temperatures and pressures. Body aerodynamics have been improved, leading to lower resistance forces from the air. Also, the internal losses of the engines, generated by friction, as well as those at the level of the tire-road interface were diminished. All these improvements to motor vehicles have led to a proportional decrease in native braking capacity. Moreover, this decrease is evident in tonnage vehicles, which are disadvantaged in terms of the small contact area of the friction elements in conventional braking systems. For these reasons as well as due to the attempts to coordinate the platoon of cars, the decrease of the fuel consumption, the increase of the safe speed of movement resulted in the necessity of the development of new auxiliary braking systems, or the improvement of the already existing ones.
