A search for alternative, sustainable tonewood species has been prompted by constraints in availability and concerns about ecological impacts associated with established sources. This article describes an effort to identify tonewood substitutes for guitar soundboards using the ANSYS Granta Selector based on derived performance objectives for physical and mechanical properties. These objectives are then combined with those for species morphology, producibility, and sustainability to arrive at sustainable and viable tonewood substitution options that meet manufacturer and customer expectations.
