木材压缩吸能特性及其压缩力学湿热效应研究进展
Research Progress in Energy Absorption Characteristics of Wood and Its Hygrothermal Effect
摘要
Abstract
Wood is a natural porous honeycomb material with excellent energy dissipation capacity,which plays an important role in energy and shock absorption in the fields such as packaging,transportation and aerospace.However,the compressive mechanical response and energy-absorbing properties of wood are affected by its multiscale structure,temperature and humidity,which limit its applications in the packaging field.Therefore,exploring the influence and mechanism of temperature and humidity on the compression energy dissipation of wood is of great significance for the scientific preparation and safe use of shock-absorbing wood.This paper firstly describes the influence of the structural composition of wood on its compression properties and energy absorption,and then summarizes and analyzes the acting patterns and influence mechanism behind the effects of environmental factors such as humidity,temperature and their coupling on the mechanical response of wood compression.In the future,more focuses should be placed upon the research on the temperature and humidity effects on the compression and energy absorption properties of wood and the intrinsic response mechanism of wood's multiscale structural composition affected by environmental temperature and humidity,in order to provide a reference for the safe use of shock-absorbing wood and optimization of the design.关键词
