The objective of this thesis is to investigate and quantify the influence of parent-twin and twin-twin interactions on the mechanical response of h.c.p. metals. To study parent-twin interactions, a mean-field continuum mechanics approach has been developed based on a double inclusion topology. A first model generalizing the Tanaka-Mori scheme to heterogeneous elastic media is applied to first and second generation twinning in Mg. The model is capable of reproducing the trends in the development of backstresses within the primary twin and enables the identification of the most likely second-generation twin variants to grow in a primary twin domain. A second self-consistent model, consisting of an extension of the first one to the case of ela...
