Quaycle.DiffusionCreepProperty — Type

System properties for plastic deformation of diffusion creep. Please refer (Hirth & Kohlstedt, 2003) for concrete units of each factor.

Fields

  • A: prefactor
  • d: grain size
  • m: grain size exponent
  • COH: water content[1]
  • r: water fugacity exponent
  • α: melting constant

  • Ω: activation volume

source
Quaycle.CompositePlasticDeformationProperty — Type

Compose all three type of plastic deformation and other strain-related system properties, see (Kohlstedt & Hansen, 2015). Each field is the overall equivalent factor not dependent on stress.

Fields

  • disl: dislocation creep
  • n: stress exponent in dislocation creep
  • diff: diffusion creep
  • peie: Peierls mechanisms
  • dϵref: reference strain rate whose length must equal strain components considered
source
Quaycle.ViscoelasticMaxwellProperty — Type

Composite property for viscoelastic rheology of maxwell representation.

Fields

  • pe::RateStateQuasiDynamicProperty: elastic rate-and-state system property
  • pv::CompositePlasticDeformationProperty: composite plastic deformation system property
source
Quaycle.compose — Method
compose(pe::RateStateQuasiDynamicProperty{T}, dϵref::AbstractVector, dϵname::AbstractVector, pvs...) where T

Create maxwell viscoelastic system given both rate-and-state and plastic properties.

Arguments

  • pe::RateStateQuasiDynamicProperty{T}: elastic rate-and-state system property
  • dϵref: reference strain rate whose length must equal to and order same as strain components considered
  • pvs...: different type of plastic deformation system properties but no more than three
source
Quaycle.composite_factor — Method
composite_factor(pv::PlasticDeformationProperty)

Compute an equivalent factor for levarage recomputing during ODE solving.

Arguments

  • pv::PlasticDeformationProperty: plastic deformation system property
source
  • 1Some references may refer it as water fugacity $f_{\mathrm{H_{2} O}}$, which is misleading. Since fugacity has the same dimension of chemical potential (Pa) while water content is dimensionless.
