국내·외 3종 소나무의 압축강도와 초음파속도와의 관계

Abstract

In this study, this treatise about relationship between compressive strength and ultrasonic velocity was using the three kinds of pines, including domestic pine and outside pine trees. as the speciman is experimentation measuring the compressive strength through nondestructive examination of wood, Pinus thunbergil Parl of domestic pine and Rusian pine, Canada pine of foreign pine were experimented as specimen of three species. measurement through ultrasonic velocity in nondestructive examination and UTM test in nondestructive examination made compressive strength presumption equation of wood about each pines, and it increased truth of experiment result according to the measurement.
