Viscoplastic plates

نویسندگان

چکیده

An asymptotic model is constructed to describe the bending of thin sheets, or plates, viscoplastic fluid described by Herschel–Bulkley constitutive law, which incorporates von Mises yield condition and a nonlinear viscous stress. The reduces number previous ones from plasticity theory mechanics in various limits. It characterized criterion proposed Ilyushin compactly combines effect moment in-plane stress tensors through three particular invariants. used explore loaded flat deflection impulsively driven circular tension-controlled beams.

Viscoplastic Modelling of Unsaturated Geomaterials

In this paper a rate dependent model for unsaturated geomaterials is presented. The formulation and numerical predictions are compared with available experimental results and discussed. The constitutive laws for the description of the time-dependent mechanical behaviour of saturated and unsaturated geomaterials generalize the isotach approach to the elastoplastic strain hardening based constitu...

Pour plates or streak plates?

The pour plate method of counting bacteria is more precise than the streak plate method, but, on the average, it will give a lower count.

The Variational Formulation of Viscoplastic Constitutive Updates

We present a class of constitutive updates for general viscoplastic solids including such aspects of material behavior as nite elastic and plastic deformations, non-Newtonian viscosity, rate-sensitivity and arbitrary ow and hardening rules. The distinguishing characteristic of the proposed constitutive updates is that, by construction, the corresponding incremental stress-strain relations deriv...

Steady-state Penetration of Viscoplastic Targets

The problem of steady-state penetration by a semi-infinite, rigid cylindrical penetrator with an ellipsoidal nose into an infinite, rigid-viscoplastic target has been studied. The target material is assumed to obey a generalized form of Von Mises yield criterion to account for the strain-rate dependence. Contact between target and penetrator is assumed to be smooth. Computed results show that t...
