description Mechanical responsiveness is an important property of core–shell carriers. To realize the quantitative design of the mechanical responsiveness of the carrier, the design and preparation of core–shell particles were carried out by combining theory with experiments. The results shows that the inner radius, outer radius, and shell elastic modulus of the core–shell particles, as well as the elastic modulus of the matrix all affect the stress distribution in the carrier-matrix region. The elastic modulus of the shell is the main material parameter that determines the mechanical responsiveness. For a carrier of a specific size, the simultaneous cracking of the carrier and the substrate can be achieved by adjusting the elastic modulus of the shell, and the theoretical design calculations were established. The theoretical design method has been verified by numerical and experimental results.
