Calculation of stresses and displacements in \(\text{Ni}_2\text{MnGa}\) have lenticular twin using tetrafunctional model with a continuous distribution of twinning dislocations at the twin boundaries. (Russian. English summary) Zbl 1300.74013
Summary: Dislocation model was developed for the calculation of the stress-strain state in a double lenticular. The model is suitable for use in the case of complex shape of the twin boundaries. Displacement fields and internal stresses caused by double lenticular in \(\text{Ni}_2\text{MnGa}\) Ni2MnGa were calculated on the based of the model in the approximation of a continuous distribution of twinning dislocations at the twin boundaries. It was found that stress is localized at the twin boundaries, and can be observed within the twin compensation voltages.
