Abstract: In this paper, based on the
fundamental theory of plastic mechanics of continuum, the
analytic formulae to express the stress field, strain field and
strain rate field for the bulging procedures under the common
action of two opposite pressures mentioned above are derived,
the effect of the pressures on stress state and bulging velocity
are discussed in comparison with the case of one single pressure
acted bulging.
Key words:
Bulging Pressure Stress state Mechanical field
