# Curing Parameters Reference ## Description Reference parameter tables for composite curing simulation. Invoke when user needs curing temperatures, friction coefficients, pressure values, or material constants. ## Content ### Complete Parameter Table | Parameter | vis Step | rub Step | glassy Step | sp Step | |-----------|----------|----------|-------------|---------| | Temperature | 150°C | 180°C | 25°C | 25°C | | Pressure | 0.6 MPa | 0.6 MPa | — | — (removed) | | Friction μ | 0.45 | 0.2 | 0.169 | — (contact removed) | | taumax | 0.118 | 0.55 | 0.118 | — | | Tool BC | U1=0, U2=0 | U1=0, U2=0 | U1=0, U2=0 | Removed | | Composite BC | — | — | — | Set-2: U1=U2=U3=0 | | Contact | Active | Active | Active | Removed | | Step time | 1.0 | 1.0 | 1.0 | 1.0 | | Initial increment | 0.1 | 0.1 | 0.1 | 0.1 | | Min increment | 1e-05 | 1e-05 | 1e-05 | 1e-05 | | Max increment | 0.5 | 0.3 | 0.5 | 0.5 | ### Material Constants #### COM (Composite Material) - **Type:** UMAT (User Material) - **Depvar:** 4 (state variables) - **User Material constants:** 1 (value=1.0) - **Expansion:** ORTHO user (orthotropic, user-defined) #### TOOL (Tool Material) - **Type:** Elastic - **E (Young's modulus):** 69000 MPa - **nu (Poisson's ratio):** 0.33 - **Expansion:** 2.52e-05 ### Mesh Parameters | Parameter | 4-ply Model | 8-ply Model | |-----------|-------------|-------------| | Elements | 2160 | 4320 | | Nodes | 3025 | 5445 | | Elements through thickness | 4 | 8 | | Element thickness | 0.25 mm each | 0.125 mm each | | Element type | C3D8 | C3D8 | | Through-thickness direction | X (-1 to 0) | X (-1 to 0) | ### Surface Definitions | Surface | Name | Description | |---------|------|-------------| | S1 | com-surface | Outer surface of composite, contact with tool | | S2 | _PickedSurf337 | Inner surface of composite, pressure application | | S4+S6 | tool-surface | Tool contact faces | ### Set Definitions | Set | Contents | Purpose | |-----|----------|---------| | Set-2 | 55 P8-1 nodes + 1 tool-1 node | Springback constraint (U1=U2=U3=0 in sp step) | | _PickedSet327 | Tool nodes | Tool U2=0 boundary condition | | _PickedSet328 | Tool nodes | Tool U1=0 boundary condition | | _PickedSet329 | All tool elements (1-1672) | Model Change removal in sp step | | _PickedSet333 | All nodes | Temperature field application |
