stochastic TPMS cellular materials

Sheet- and ligament-based stochastic cellular materials have better isotropic characteristics than periodic cellular materials.

At higher relative densities, stochastic sheet- and ligament-based cellular materials exhibit thermal conductivity and elastic properties similar to periodic equivalents.

At lower relative densities, periodic sheet- and ligament-based cellular materials show superior thermal conductivity and elastic characteristics compared with stochastic counterparts.

Ligament-based cellular materials have inferior thermal conductivity and elastic properties compared with sheet-based cellular materials of the same relative density.

A stochastic TPMS-based design process can yield stochastic cellular materials with enhanced elastic characteristics relative to spinodal cellular materials when a suitable topology is employed.

The study numerically investigates effective anisotropic elastic properties and thermal conductivity of stochastic-TPMS and spinodal cellular materials using the finite element method.
