The weldability of materials is still for many years a highly contentious issue, particularly regarding the causes of the hot crack formation. Because of the process-related temperature and emissions, direct measurement for the arising strain in the close vicinity of the welding process is challenged. Therefore, the externally loaded hot cracking tests remain for decades the only way to determine...
In the given paper the effective simulation technique of quartz oscillators the in time domain with use of general purpose EDA software (PSPICE, MicroCAP, etc) is offered. The main idea is reception of averaged on the first harmonic parameters of nonlinear active part of self-oscillating circuit with the help of widespread programs of circuit simulation, with the subsequent analysis of complete self-oscillatory...
