Simulation results for the distribution of flow-induced wall stresses within 36 different porous scaffolds with porosity larger than 80% indicate that the normalized wall stress follows a single gamma distribution. Experimental and computational results for scaffolds prepared via different techniques from different materials and by other laboratories follow the same distribution. The form of this universal distribution is offered, as well as the methodology to obtain it for laminar flow through high porosity materials.
