摘要
本文以一种大端面仿生结构集成材为对象,利用静态法,在恒定外力的载荷作用下,测定不同端面尺寸集成材静态弹性模量。研究结果表明:集成材的变形程度随着载荷的增加逐步增加;但进入循环加载过程后,试件处于弹性工作阶段,变形微小;循环过程结束后,载荷持续增加,试件出现轻微响声,变形加剧。大端面集成材顺纹抗压弹性模量值为7~8 GPa左右,且随着集成材尺寸的增加,弹性模量呈下降趋势。
The compressive mechanical property of bionic structure glulam with large cross-section wastested by static method to reveal the effect of size on the static elastic of modulus. The results showed thatthe deformation gradually increased with the increasing of load,but the specimens were in a flexible work-ing phase with the tiny deformation when entering the cyclic loading process;the aggravated deformationwere encountered with the continued increasing load when the cyclic loading process was terminated. Theresults of this research also revealed that the compressive modulus of elasticity parallel to grain was about7 ~ 8 GPa which decreased with the increasing of size of specimens.
