1. A process for making a layered multi-material structural element having controlled mechanical failure characteristics, the process comprising the steps of:
supplying a cementitious layer and forming a polymer layer on the cementitious layer by additive manufacture such that the polymer layer has a first thickness and the cementitious layer has a second thickness;
wherein the polymer layer comprises a polymer comprising a liquid crystal elastomer and the cementitious layer comprises a cementitious material;
allowing the polymer from the polymer layer to suffuse into the cementitious layer for a period of time to obtain a suffused zone in the cementitious layer such that the suffused zone has a third thickness that is less than half the second thickness; and
using a stimulus to manipulate the suffused zone, wherein the stimulus is selected from the group consisting of a temperature change, electric field, magnetic field, radiation, and any combination of the same.
