摘要
This study investigated the effect of a compressive load of 0.092 MPa on the history of the tangential strains in Japanese larch (Larix leptolepis Gordon) log cross sections subjected to external compressive load during radio-frequency/vacuum drying. The external compressive load of 0.092 MPa played a role in inducing cracking in the outer zone of the log cross section, combining with other tensile strains. However, it also played a role in reducing the heart checks in the core of log cross section when exerted on the cross section of log cross section.
