    The state of deformation and stress in the sealing elements is of high importance for the projecting of the sealing rings on the electronic covers in a plane. Modeling is required in order to predict the pressurization in ...
  • Beygelzimer, Y.; Lavrinenko, N. (Физика и техника высоких давлений, 2012)
    A mechanism of perfect plasticity is suggested that implies the phenomenon under study to be of ctitical nature. We consider that it is related to percolation transition in the net of grain boundaries and with nonlocal ...
