When the wheel/rail surfaces contacted, the rail contact surface is subjected to high frictional force and the plastic flow
If [theta] [not equal to] [phi], the material is nonassociated, and there exists an angle [phi] - [theta] between the plastic flow
direction and the yield surface, as shown in Figure 1(a).
When the material reaches the plastic flow
conditions, the plastic yield stress decreases and the yield point is attained in advance with the increasing crack length.
This paper contains numerical analysis of influence of the die roughness on the material plastic flow
during compression in dry conditions in the microscale--size effect.
Plastic: plastic is a process of heating and being in a state of plastic flow
. The melt injection mold cavity should be heated to the required temperature, the temperature requirement is uniform.
Following the observation by Mindel and Brown that the stress dependence of flow is independent of strain , it can be rationalized [24, 25] that a similar relation is found for the product of time-to-failure and the plastic flow
rate during secondary creep, [[??].sub.pl], implying that:
Rheology is the study of the flow of matter, primarily in a liquid state, but also as soft solids or solids under conditions in which they respond with plastic flow
rather than deforming elastically in response to an applied force.
The velocity field from an exact semianalytical solution for plastic flow
through an infinite wedge-shaped channel derived in  is adopted as one of the kinematically admissible velocity fields.
The accelerated patch hits the substrate at an oblique angle where the high impact velocity induces plastic flow
at the film-substrate interface.
Himalayan hinterland-verging superstructure folds related to foreland-directed infrastructure plastic flow
: insights from centrifuge analogue modelling.
The top of the bottle has a plastic flow
restrictor (a round plastic disc with small hole for the syringe) to help prevent parents from accidentally overdosing.
