AbstractTrussTheory
Abstract type for truss theory variants.
Truss elements carry only axial forces (tension/compression), no bending.
# Concrete Theories
- `SimpleTruss`: Standard 2-node truss (axial force only)
# Future Extensions
- `CableTruss`: Cable elements (tension only, no compression)
- `PretensionedTruss`: Trusses with initial stress
# See Also
- [`TrussFormulation`](@ref)

SimpleTruss <: AbstractTrussTheory
Simple truss theory (axial force only).
Assumptions:
- Only axial forces (tension/compression)
- No bending moments
- Pin-jointed connections
- 3 DOFs per node in 3D: (ux, uy, uz)
- 2 DOFs per node in 2D: (ux, uy)
# Usage
```julia
formulation = TrussFormulation{SimpleTruss}()
physics = Physics(
formulation=formulation,
field=Displacement{3}(), # 3D truss
mesh=truss_mesh,
material=steel
)
```
"""
struct SimpleTruss <: AbstractTrussTheory end
"""
TrussFormulation{Theory<:AbstractTrussTheory} <: AbstractFormulation
Truss element formulation with theory variant.
# Type Parameter
- `Theory`: Truss theory type (SimpleTruss, CableTruss, etc.)
# Examples
```julia
# Standard truss
TrussFormulation{SimpleTruss}()
```
# Fields per Node
- 3D: 3 DOFs (ux, uy, uz)
- 2D: 2 DOFs (ux, uy)
Use with `Displacement{Dim}` field type.
