Dynamic Young's modulus and glass transition temperature of selected tropical wood species

Dynamic Young's modulus (Ed) of selected tropical wood species, namely Oyera polyphylla, Endospermum diadenum, Cratoxylum arborecens. Alstonia pneumatophora, Macaranga gig antea and Com mer sonia bartramia, used for the study was measured using the free-free flexural vibration method. Young...
