.. _auto_dynakeyword_mat36e:

*CREATE A MAT_36E*
==================

Generates an LS-DYNA MAT_036 (*MAT_3-PARAMETER_BARLAT) keyword block for anisotropic elastic-plastic sheet materials. Supply material constants and per-direction hardening curves; the worker assembles the formatted keyword text ready for deck inclusion.

When to use
-----------

Classification: **data**.

Tagged: ``MAT_3-PARAMETER_BARLAT``, ``anisotropic``, ``barlat``, ``hardening``, ``keyword``, ``ls-dyna``, ``mat_036``, ``mat_36``.

Inputs

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Material Name
     - material_name
     - scalar
     - —
     - 
     - Alphanumeric label written into the MAT_36 keyword header (e.g. 'DP600_rolled'); leave blank to omit a name field.
   * - Material ID
     - material_i_d
     - scalar
     - —
     - 
     - Integer material ID referenced by element sections in the deck; must be unique within the model — leave blank to assign automatically.
   * - Density
     - density
     - scalar
     - —
     - 
     - Mass density of the material in model-consistent units (e.g. kg/mm³ or t/mm³); required for any dynamic analysis.
   * - Elastic Modulus
     - elastic_modulus
     - scalar
     - —
     - 
     - Young's modulus in model-consistent pressure units (e.g. MPa); governs elastic stiffness before yielding.
   * - Poissons Ratio
     - poissons_ratio
     - scalar
     - —
     - 
     - Poisson's ratio (dimensionless, 0–0.5); controls lateral strain coupling in the elastic regime — typical steel value is 0.3.
   * - Starting Curve Id
     - starting_curve_id
     - scalar
     - 1
     - 
     - Integer ID assigned to the first load-curve generated for this material; subsequent curves are numbered consecutively from this base — default is 1.
   * - Number Of Dig Points
     - numberof_dig_points
     - scalar
     - 200
     - 
     - Number of discrete points used to digitise each hardening curve when writing the *DEFINE_CURVE entries; default 200 is sufficient for most applications; reduce for smaller deck size.
   * - R00 Hardening Curve
     - r00hardening_curve
     - vector
     - —
     - 
     - True stress vs. true plastic strain hardening curve measured (or fitted) in the rolling direction (0°); provided as an XY vector or curve object.
