p_spring
Purpose
Element property function for spring and rigid elements
Syntax
il=p_spring('default')
il=p_spring('database MatId Value')
pl=p_spring('dbval MatId Value')
il=p_spring('dbval -unit TM ProId name');
Description
This help starts by describing the main commands : p_spring Database and Dbval. Supported p_spring subtypes and their formats are then described.
[Database,Dbval] ...
Element properties are described by the row of an element property matrix or a data structure with an .il field containing this row (see section 7.4).
Examples of database property construction
il=p_spring('database 100 1e12 1e4 0')
il=p_spring('dbval 100 1e12');
il=fe_mat('convert SITM',il);
il=p_spring(il,'dbval 2 -unit TM 1e12')
p_spring currently supports 2 subtypes
1 : standard
[ProID type k c b m]
| ProID |
property identification number |
| type |
identifier obtained with fe_mat('p_spring','SI',1) |
| k |
stiffness value |
| m |
mass value |
| c |
viscous damping value |
| eta |
loss factor |
| S |
stress coefficient |
2 : bush
[ProId Type k11:k66 c11:c66 eta Mass Volume]
| ProID |
property identification number |
| type |
identifier obtained with fe_mat('p_spring','SI',2) |
| ki |
stiffness for each direction |
| ci |
viscous damping for each direction |
