How do you calculate strain rate in Abaqus?
How do you calculate strain rate in Abaqus?
Strain rate in ABAQUS? I want to perform high strain rate simulations in ABAQUS using Crystal Plasticity UMAT.
What is equivalent plastic strain in Abaqus?
The equivalent plastic strain is equal to the absolute value of the axial plastic strain in uniaxial tension or compression.
What is meant by strain rate?
Strain rate is the rate of deformation caused by strain in a material within a corresponding time. This gauges the rate where distances of materials change within a respective period of time.
How do you extract strains in Abaqus?
For one given element, you can extract any strain and stress time curve. In the “Tools” menu of the postprocessor, select “XY Data” then “Create”. Select “ODB field output” or “ODB history output” depending on how you chose to stock the results you want to combine.
What is Mises stress in Abaqus?
Von Mises stress is a value used to determine if a given material will yield or fracture. It is mostly used for ductile materials, such as metals.
What is the Johnson-Cook constant?
The Johnson-Cook equation has five constants: A, B, C, n and m [1, 4]. These five constants are charac- teristic for the given material. Information about these five constants can be used for calculating material dynamic response during plastic deformation.
What is Johnson-Cook parameters?
The Johnson–Cook material model is one of the simplest models with five parameters, which can describe the material behaviour at high temperatures, high strains, and high strain-rates and is often used in machining simulations.
What is PE and PEEQ in Abaqus?
PE Plastic Strain. PEEQ Equivalent Plastic Strain : a scalar variable that is used to represent the material’s inelastic deformation. Cite. 8th Jan, 2021.
Do creep and plasticity interact in Abaqus/Standard?
If creep and plasticity occur simultaneously and implicit creep integration is in effect, both behaviors may interact and a coupled system of constitutive equations needs to be solved. If creep and plasticity are isotropic, Abaqus/Standard properly takes into account such coupled behavior, even if the elasticity is anisotropic.
What is raterate-dependent gasket behavior in Abaqus/Standard?
Rate-dependent gasket behavior in Abaqus/Standard: uses unidirectional creep as part of the model of the gasket’s thickness-direction behavior; can be defined using user subroutine CREEP or by providing parameters as input for some simple creep laws;
Is it possible to display total strain components (E) in Abaqus?
As my analysis is based on a crimping step where NLGEOM=on (thus including non-linear effects due to large plastic deformations), the software Abaqus Standard/Explicit 6.16 is not able to display the Total strain components (E) although it is requested in the Field Output Requests.
Is cycyclic hardening supported in Abaqus/CAE?
Cyclic hardening is not supported in Abaqus/CAE. Alternatively, and as the only means of defining rate-dependent yield stress for the Johnson-Cook and the crushable foam plasticity models, the strain rate behavior can be assumed to be separable, so that the stress-strain dependence is similar at all strain rate levels: ( 0, θ, f i) = 1.0 ).
