Resum

Finite elements modelling (FEM) is used to simulate the compression response of core-shell microcapsules with an elastic-perfectly plastic wall material. Three methods are presented to calculate the yield stress of the material from experimental compression force curves. Dry melamine-formaldehyde microcapsules compressed using a micromanipulation technique were used as experimental validation. The calculated yield stress with the different methods all agreed within sample variability, at ~130. MPa.
