Abstract
Based on this scientifically established concept, the head of the project has provided in previous works that the magnitude of component deformation, usually measured in single or biaxial exertion conditions during test, represent a projection of some vector-function in the deformation space. It is established that the module of the vector-function is numerically equal to the size of the effective deformation (intensive deformation), while its change describes the character of accumulation of the total deformation in the element under consideration and its initial blank. The direction of the vector-function is unambiguously determined by the scheme of stress condition and, depending on it, can take any value between 0 and 360 degrees. Thus it is possible to manage the character of accumulation of deformation by changing the scheme of stress condition. Thereby it is possible to realize the process of deep drawing of molybdenum sheet with levels of deformation up to 60-80%, with an initial expansion lengthening characteristic of molybdenum sheet being no more than 2-5%.
