Description: We solve the magnetostriction strains for B20 helimagnets in the skyrmion crystal phase. By taking MnSi as an example, we reproduce its temperature-magnetic field (T-B) phase diagrams within a thermodynamic potential incorporating magnetoelastic interactions. The calculation shows that the normal strain 33 undergoes a sudden jump through a conical-skyrmion phase transition at any temperature. The corresponding experimental measurements for MnSi agree quantitatively well with the calculation.
