工程用生物基材料力学性能研究

Review of mechanical properties of bio-based materials for engineering

工程用生物基材料具有轻质、高强、美观、力学性能优越的特点,是极具应用潜力的绿色建筑材料。工程用生物基材料主要分为工程用木基材料和工程用竹基材料两大类。基于已有研究分别对工程用木基材料和工程用竹基材料的抗拉、抗压、抗剪、抗弯等力学性能进行总结,分析两者本构模型的优缺点、归纳各力学指标的概率分布,总结基于可靠度的设计方法,发现工程用木基材料的力学研究涵盖的材料较为充分,但是工程用木基材料的本构模型和设计方法有待进一步研究。

Bio-based materials for engineering have the characteristics of light weight,high strength,beautiful appearance,and superior mechanical properties,and are green building materials with great application potential.Bio-based materials for engineering are mainly divided into two categories:wood-based materials for engineering and bamboo-based materials for engineering.Based on the existing research,this paper summarizes the mechanical properties of wood-based materials for engineering and bamboo-based materials for engineering,such as tensile,compressive,shear,and flexural properties,respectively analyzes the advantages and disadvantages of the two constitutive models,and summarizes the mechanical properties of the two constitutive models.The probability distribution of indicators,summarizing the design method based on reliability,it is figure out that the mechanical research of engineering wood-based materials is relatively sufficient,and the constitutive model and design method of engineering wood-based materials need further research.
