The Extrusion
, BlowMolding
, and
BlowMolding_viscoelastic
directories contain material
data files that incorporate generic or relevant rheological and thermal data for
common materials, such as LDPE, HDPE, PVC, and PS. Each of these directories is
specialized for the application and model suggested in the corresponding directory
name. More precisely, the Extrusion
directory contains
material data files to be used for the simulation of extrusion flows in which a
generalized Newtonian fluid model is invoked. The
BlowMolding
directory contains material data files to
be used for the simulation of blow molding cases in which a Newtonian fluid model is
invoked, for 2D and 3D geometries, as well as for shell simulations. The
BlowMolding_viscoelastic
directory contains material
data files to be used for the simulation of blow molding cases in which an integral
KBKZ fluid model is invoked for shell simulations.
In each of these directories, you can find data files for common materials. The file names are designed to allow easy identification, and to conform to a structure or nomenclature. The name structure consists of the following: the process being simulated, the generic name of the material, the thermal attribute, and the temperature. The thermal attribute conveys whether the data is for isothermal or nonisothermal conditions; in the latter case, additional thermal parameters are provided in the file. For isothermal data, the selected temperature is used in the name; for nonisothermal data, it is the reference temperature that is used in the name.
For example, in the Extrusion
directory, you will find
files like Extrusion_LLDPE_isoth_463K.mat
and
Extrusion_LLDPE_nonisoth_463K.mat
; these files contain
relevant data for LLDPE, which can be used for the simulation of an extrusion
process under isothermal and nonisothermal conditions, respectively. For the
isothermal condition, the selected temperature is 463 K, while for the nonisothermal
condition, the rheological data is provided at a reference temperature of 463 K, and
incorporates a temperature dependence.
