Abstract

Abstract Swelling (Sw) and shrinking (Sh) of Larix kaempferi and Cryptomeria japonica woods were observed with the methods digital caliper, image analysis, and digital image correlation (DIC) as a function of cubic sample sizes (203, 503, and 1003 mm3) and the three anatomical directions of wood. The moisture content (MC) of the samples was 19, 12, and 8%, such as MC→ and MCsatur. Coefficients of swelling were significantly different at the three sample sizes. Coefficients of shrinking were significantly different by species and sample size. Results of DIC revealed that the magnitude of mixed Sw/Sh behaviors increased with increasing sample size.
