You can plot displacement components of buckling mode shapes:
UX |
Displacement in the X-direction |
UY |
Displacement in the Y-direction |
UZ |
Displacement in the Z-direction |
URES |
Resultant displacement (does not use the reference geometry) |
Mode shapes illustrate the profile of the mode only (i.e., the displacement of nodes relative to each other). The displacement values are calculated based on various normalization procedures. The software normalizes each mode shape such that {φi}T [KG] {φi} is equal to [I], where {φi} is the vector representing the ith mode shape, {φi}T is its transpose, [KG] is the geometric stiffness matrix, and [I] is the unity matrix..
