Struct TwoWayShapeMemory 

pub struct TwoWayShapeMemory {
    pub model: BrinsonModel,
    pub two_way_fraction: f64,
    pub training_cycles: u32,
    pub max_two_way_fraction: f64,
    pub saturation_rate: f64,
}

Two-way shape memory effect: the material spontaneously deforms during both cooling and heating without external load, after training.

The trained material has internal residual stresses from dislocation arrays that bias the variant selection during cooling.

Fields

model: BrinsonModel

Brinson model for constitutive relations.

two_way_fraction: f64

Two-way recoverable strain (fraction of h_max, typically 0.2-0.5).

training_cycles: u32

Number of training cycles completed.

max_two_way_fraction: f64

Maximum two-way fraction after saturation.

saturation_rate: f64

Training saturation rate constant.

Implementations

impl TwoWayShapeMemory

pub fn new(model: BrinsonModel) -> Self

Create a new two-way shape memory model.

pub fn train_cycle(&mut self)

pub fn cooling_strain(&self, temp: f64) -> f64

Spontaneous strain on cooling to T < Mf (no external load).

pub fn heating_strain(&self, temp: f64) -> f64

Spontaneous strain on heating to T > Af (recovery).
