Type
|
1
|
1 is polybeams
2 is plates modeled as polybeams (for example, PLT)
3 is for parts which are not unfolded and follow the old polybeam calculation (for example, the line 3 L* * disables unfolding of L profiles)
|
Profile
|
HE300A
|
You can also use wildcards with profile, for example, HE300*.
|
Material
|
S235JR
|
You can also use wildcards with material, for example, S235*.
|
Rotation / thickness min
|
0
|
For polybeams: the minimum angle when the profile is rotated around its longitudinal axis
For plates: the minimum thickness of plate
|
Rotation / thickness max
|
180
|
For polybeams: the maximum angle when the profile is rotated around its longitudinal axis
For plates: the maximum thickness of plate
|
Flag
|
2
|
This property defines what kind of parts are affected by the next two properties.
1 is sharp folds. Only polybeams with straight chamfers are affected.
2 is curved bends. Only polybeams with curved chamfers are affected.
|
Angle / radius min
|
0
|
For sharp folds: the minimum angle
For curved bends: the minimum radius
|
Angle / radius max
|
1000
|
For sharp folds: the maximum angle
For curved bends: the maximum radius
|
Ratio
|
.7
|
Defines how much the profile stretches or shrinks when unfolded.
Ratio = (1 - the relative location of the neutral axis).
If only the inner surface of the profile shrinks, the ratio is 1. If only the outer surface of the profile stretches, the ratio is 0. By default, the ratio is 0.5 for length calculation and 0.0 for bending radius calculation.
Tekla Structures applies the unfolding ratio if the profile properties are within the range indicated by the minimum and maximum values.
