We derive geometrically linear elasticity theories as $\Gamma$-limits of rescaled nonlinear multi-well energies satisfying a weak coercivity condition, in the sense that the standard quadratic growth from below of the energy density $W$ is replaced by the weaker p-growth far from the energy wells, where $1
