PELAS (Elastic Element Property)

Description

The PELAS entry specifies the stiffness and stress coefficient of a spring element (CELAS1 or CELAS2 entry).

Format

1 2 3 4 5 6 7 8 9 10
PELAS PID K GE optional PID optional K optional GE optional optional unused

Example

PELAS 24 1.+3
Field Definition Type Default
PID Property identification number. Integer > 0 Required
K Elastic property value. Real Required
GE Structural element damping coefficient. See Remark 4. Real or blank 0.0

Remarks

  1. PELAS entries must all have unique property identification numbers.
  2. The use of negative spring values may result in fatal errors.
  3. One or two elastic spring properties may be defined on a single entry.
  4. To obtain the damping coefficient GE, multiply the critical damping ratio C/C0, by 2.0.
  5. If PARAM, W4 is not specified, GE is ignored in transient response analysis. See the Parameters section for more information on W4.
