Angiosperm leaf venation is based on two major patterns, typically dicotyledonous branching and monocotyledonous parallel veins.
The influence of these patterns on deformation and fracture properties is poorly understood.
In this paper, three species of dicotyledons with netted venation and three species of monocots with parallel venation were selected, and the effect of vein distribution of leaves on their mechanical properties and deformation behavior was investigated.
Whole images of leaves were captured using a digital camera, and their vein traits were measured using the image processing software Digimizer.
A self-developed mechanical testing apparatus with high precision and low load was used to measure the tensile properties of leaves.
The deformation behavior of the leaf was captured using a digital microscope during the tensile test.
Results showed that the vein architecture of monocots and dicots is different, which had a remarkable effect on their mechanical properties, deformation behavior, and crack propagation behavior.
The greater the diameter and the more the number of veins parallel to the tensile direction, the higher the tensile force, tensile strength, and elastic modulus of the leaves.
The netted venation leaves evinced the elastic-plastic fracture type, and the hierarchy venation provided resistance to fracture propagation of cracks in the leaves by lengthening the crack path.
The leaves with parallel venation behaved in a predominantly brittle manner or elastic fracture type, and the parallel venation inhibited the initiation of cracks in the leaves by increasing the load at complete fracture of the leaves.
The investigation provides reference for a stiffened plate/shell structure and bionic anticrack design.
