FiberElement

FiberElement(y_loc: float, z_loc: float, area: float, material: Union[int, str, Material])

Represents a single fiber in a fiber section.

A fiber is the smallest unit of discretization in a fiber section, defined by its position (y, z) and its area. Each fiber is associated with a material response.

Tcl form

fiber <yLoc> <zLoc> <area> <matTag>

Attributes:

Name	Type	Description
`y_loc`		Local y-coordinate of the fiber center.
`z_loc`		Local z-coordinate of the fiber center.
`area`		Cross-sectional area of the fiber.
`material`		Resolved Material object for the fiber.

Example

from femora.core.model import Model
import femora.components.section.fiber  # noqa: F401

model = Model()
mat = model.material.uniaxial.steel01(
    user_name="S",
    Fy=50.0,
    E0=29000.0,
    b=0.01,
)
section = model.section.fiber.section(user_name="BeamFiber")
section.add_fiber(y_loc=0.5, z_loc=0.5, area=0.1, material=mat)
print(section.fibers[0].to_tcl())

Create a FiberElement with validated coordinates and area.

Parameters:

Name	Type	Description	Default
`y_loc`	`float`	Local y-coordinate.	required
`z_loc`	`float`	Local z-coordinate.	required
`area`	`float`	Fiber area.	required
`material`	`Union[int, str, Material]`	Uniaxial material reference (object, tag, or name).	required

Raises:

Type	Description
`ValueError`	If coordinates or area are not numeric, if area is non-positive, or if the material cannot be resolved.
