TABLEMD

Bulk Data Entry Defines a multi-dimensional tabular function which identifies single or multiple X-values for a single Y-value.

Definitions

Field Contents SI Unit Example
TID/LABEL Table identification number or a user-defined string label for this TABLEMD Bulk Data Entry. 3

No default (Integer > 0 or <string>)

  
NDEP Identifies the number of dependencies (Xi_j) defined for each Yi value.

No default (Integer > 0 and ≤ 10)

  
Yi Yi values.

No default (Real or ENDT)

  
Xi_j Xi values for each corresponding Yj value. 4, 5

No default (Real or ENDT)

  
FLAT Specifies the handling method for looking up Yi-values when specified Xi is outside the range of Xi-values in the table.
= 0
If an Xi-value input is outside the range of Xi_j values specified on the table, the corresponding Yi-value lookup is performed using linear extrapolation from the two start or two end points.
= FLAT or 1
If an Xi-value input is outside the range of Xi_j values specified on the table, the corresponding Yi-value is set equal to the start or end point, respectively.

Default = 1

  

Comments

  1. At least one continuation entry must be specified.
  2. When TABLEMD is used in OSTTS damage calculations, NDEP=1 should be specified. The Xi_j values should be specified in ascending order only.
  3. String-based labels allow for easier visual identification of TABLEMD, including when being referenced by other entries (for instance, the TID field of material data like MATS1 and MATF entries). Refer to the String Label Based Input File for more information.
  4. For a particular Yi, if certain Xi_j fields are blank on the TABLEMD entry, the default value for such Xi_j is set as 0.0. The final Xi_j value defined for a particular Yi should not be left blank.
  5. The Xi_j values should be in ascending order. Further, for each Xi_j, the previous Xi-1_j column must be in ascending order.
    In Figure 1:
    • X3_j = {100.0, 150.0}.
    • Now, for X3_j = 100, the corresponding X2_j values are in ascending order; X2_j = {0.0362, 0.16864, 3.52993}.
    • Similarly, for X2_j = 0.0362, the corresponding X1_j values are in ascending order; X1_j ={0.0, 1.3938-3, 2.4753-3, 3.8828-3, 5.1382-3}.
