This paper deals with the numerical determination of the stress intensity factor KI for meridional cracks on the ellipsoidal head of pressure vessels. The experiment was carried out according to selected parameters, including vessel diameter, wall thickness and pressure. The analysis of the results concluded that the cylindrical segment of the elli...

In this paper, a differential equation is derived relating to the relationship among the Loschmidt constant, the Avogadro constant, and the speed of sound in gases as a function of the thermodynamic properties of the gas (pressure, temperature, and volume). To confirm the validity of the derived equation, the ratio of the constants NL/NA and the de...
