中密度纤维板（Medium Densify Fiber Board，简称MDF）是一种由木纤维和环氧树脂组成的复合材料，其典型密度范围为600-800 kg/m3。它目前用于建筑物中的二级结构，如建筑墙壁和立面。MDF通常以平板形式提供，其可以切割成各种形状用于建筑设计目的。一种切割方法被称为切口，其中在木板上进行一系列切割以主要通过弯曲和扭曲变形来产生柔性结构。在这项研究中，我们提出了一个微观力学模型的切割模式，以了解整体变形的切口面板。三种不同的切割密度，即，研究了正方形螺旋图案的每四分之一晶胞的一个、两个和三个切口。研究了不同切割密度对单胞单轴拉伸的影响。对单胞进行了单轴拉伸实验。并对试验和模型的响应进行了比较。
Medium densify fiberboard (MDF) is a composite comprising of wood fibers and epoxy resin, with a typical density range between 600-800 kg/m3. It is currently used for secondary structures in buildings such as architectural walls and facades. MDFs are typically available in flat panel forms which can be cut into various shapes for architectural design purposes. One cutting method is known as kerfing, in which a series of cuts are made on a wood panel to create flexible structures mainly through bending and twisting deformations. In this study, we present a micromechanics model of cut patterns in order to understand the overall deformations of the kerf panel. Three different cut densities, i.e., one, two, and three cuts per quarter unit-cell, of a square spiral pattern are studied. The effect of different cut densities on the uniaxial stretching of the unit-cell is examined. An experimental test is also done on a unit-cell under uniaxial stretching. The responses from the experiment and model are compared.
