In the field of timber load-bearing structures, adhesive bonding is a promising joining technique that may increase the structural stiffness and capacity of timber joints and structures. The use of ductile adhesives may furthermore allow designing ductile joints, which can compensate for the material ductility that timber lacks. To demonstrate the potential of this approach, adhesively-bonded double-lap timber joints were manufactured using a ductile acrylic adhesive and then subjected to axial tension and compression loading. The load-displacement responses were measured and compared to those of the same joint configuration for which a brittle epoxy adhesive was used. The effect of the different adhesives on the joint capacity and ductility has been studied and quantified. Strain field measurements using the Digital Image Correlation (DIC) technique and a quadratic strain interaction criterion provided a better understanding of the mechanical behavior of the two different joint types.

在木材承重结构领域，粘合剂粘结是一种有前途的连接技术，可以增加木材接头和结构的结构刚度和承载能力。延展性粘合剂的使用还可以允许设计延展性接头，其可以补偿木材缺乏的材料延展性。为了证明这种方法的潜力，使用可延展的丙烯酸粘合剂制造了粘合双搭接木材接头，然后对其施加轴向张力和压缩载荷。测量了载荷-位移响应，并将其与使用脆性环氧粘合剂的相同接头构型进行了比较。已经研究和量化了不同粘合剂对接缝能力和延展性的影响。
