Fracture of the breakable isostatic graphite is concerned using the experimental and theoretically, the plates containing nicks holes key subject to varying degrees of mixed task. The main purpose of this work is a double one. In the first place, in order to offer a new set of experimental results on fracture of samples of graphite scored, with different values of the load mixed and radii notch and which may be helpful for researchers, as it enlarges the very limited data available; and secondly...

Fatigue is a process (succession of mechanisms) which under the action of time-varying strains or deformations modifies the local properties of a material. These can lead to the formation of cracks and eventual rupture of the structure. Fatigue is in particular characterized by an extent of variation in stress which may be well below the yield strength of the material. The main stages of fatigue failure of an assembly are the initiation of cracks (if defects are not already present in the materi...

Distributions of stress 3D in the vicinity of the overlapping corners of joints with a single lap were investigated with accuracy at present the man. A (Fe), model accurately Finite Element 3D has been carried out in order to investigate the intensity of the stress of adjustments in the plan and outside of stress by the width of the plate. The influences of the thickness of the adhesive and the Poisson distribution have been taken into account. Numerical results showed the presence of modes enga...

Three dimensions or three-dimensional or 3D are expressions that characterize the space around us, as perceived by our vision, in terms of width, height and depth. The term "3D" is also (and improperly) used to refer to the representation in synthetic (digital) images, the relief of stereoscopic images or other images in relief and sometimes even the simple stereophonic effect, which Can only render 2D (it is therefore only the calculation of the projected projections, the shadows, the rendering...

It is an entry technique in use recently, albeit in selected centers and represents a further step in the field of minimally invasive surgery. Basically it has the same indications but, at present, is reserved for selected patients. Compared to traditional video-assisted surgery presents some important differences. The surgeon is physically distant from the operative field and sits at a console, equipped with a monitor, from which, through a complex system, controls the movement of the robotic a...

In this study, the theoretical principles necessary to determine the exact magnitude of a moving electron, depending on the speed of movement, will be exposed. The equations are specifically discussed to determine the radius R of the moving electron, which refers to the electron movement velocity v and the resting mass m0. The mechanical moment of inertia of a sphere around one of its diameters is determined by the relationship between the total kinetic energy of a moving electron as the sum of ...

This paper describes an application of industrial robots that gain ground mainly in the aerospace industry. It is a TTT manipulator whose task is to automatically position the end-effector, in this case a complex sensor system and a eddy-current probe in the position set by the software application for testing by non-destructive ultrasound control of tickets and bars of titanium, both round and square, or any other transparent ultrasound metal (obviously in a certain range of sizes). For surface...

The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically called rigid memory mechanisms, are mechanical transmissions widely used in the economy for many yea...

The paper presents a method of the original type in order to determine the effectiveness of a mechanism camshaft and adept. The originality of this method consists of eliminating the friction. In this research analyzes the four types of side camshaft: 1. Camshaft rotary switch and the motherboard translated adept; 2. The mechanism with the camshaft rotary switch and openness to be translated with roll; The 3. The camshaft rotary switch and the rocking chair adept with roll; The 4. The camshaft r...

Nearly all models studying the dynamic of gearing with parallel axes are based on classical mechanical models and known which are studying the spinning vibration of shafts gears and determine their own beats and strains of shafts spinning. These classical dynamic models are very useful, but they didn't take in consideration the dynamic events formed between the two teeth in contact (or more pairs of teeth in contact). It's not seen the physiology of the mechanism itself with toothed gears. In th...
