Compressive response of self-healing polymer foams containing bilayered capsules: Coupled healing agents diffusion and stress simulations

Numerical modelling on the compressive response of self-healing polymer foams embedded with novel, bilayered alginate capsules was developed based coupled pore fluid diffusion and stress simulations. Micromechanical models were to link damage variable permeability as well saturation capillary pressure within damaged foams. These micromechanical calibrated against experimental measurements implemented into To give physical insight how evolution mass conservation, an illustrative example presented for one-dimensional (1D) compression problem. Two-dimensional (2D) detailed finite element simulations conducted interpret findings. It demonstrated that numerical study could capture main features process. The predicted healing efficiency has good agreement measured by experiments. Based models, parameter understand effects key design parameters system.
