复合材料层合板建模共有3 种方法，分别为： 1. Conventional shell composite layups 2. Continuum shell composite layups 3. Solid composite layups 3 种不同方法的具体介绍请参考 Abaqus/CAE User’s Manual 12.13 Creating and editing composite layups 1. 采用 conventional shell element 建立 composite layups 1.1 建立 part-1，Creat Part: 3D, Deformable, Shell 1.2 建立 Material-1，Mechanical: Elasticity: Elastic: Type=Lamina,在 data 中输入材料参数：E1=25.0E6 E2=1.0E6 Nu12=0.25 G12=0.5e6 G13=0.5E6 G23=0.2E6 1.3 建立Composite Lay u p, Composite Layup Manager: Create: Initial ply count=4 Element Type=Conventional Shell, 生成4 层的具体数据如下图所示 1.4 生成Instance, Create Instance: Parts=Part-1 Instance Type=Independent: OK 1.5 生成Step, Create Step: Procedure type=Static, General: Basic: Nlgeom=off 1.6 建立 Load, Create Load: Step=Step-1 Mechanical=Concentrated force: CF1=1000 1.7 建立Bou ndary Condition， Create Boundary Condition: Step=Step-1 Mechanical=Displacement/Rotation: U1=0 U2=0 U3=0 UR1=0 UR2=0 UR3=0 1.8 建立Mesh，Mesh Type: Element Type=S8R 1.9 建立Job， Create Job: Name=Job-1 Model=Model-1: Submit 1.10 查看计算结果 Visualization: Plot Contours on Deformed Shape:U Magtinude 2. 采用Solid element 建立Solid Composite Lay u ps 2.1 建立part-2，Creat Part: 3D Type=Deformable Shape=Solid Extrusion: Depth=0.8(注：这里的 Depth 是 Composite Layup 的总厚度) 2.2 建立Material-1，Mechanical: Elasticity: Elastic: Type=Engineering Constants 在 data 中输入材料参数：E1=25.0E6 E2=1.0E6 E3=1.0E6 Nu12=0.25 Nu13=0.25 Nu23=0.25 G12=0.5e6 G13=0.5E6 G23=0.2E6 2.3 建立Composite Lay u p, Composite Layup Manager: Create: Initial ply count=4 Element Type=Conventional Shell , 生成 4 层的具体数据如下图所示(注：参数 Element Relative Thickness 为相对于总厚度的比例，并不是实际厚度，其总和可以不为1) 2.4 生成 Instance, Create Instance: Parts=Part-1 Instance Type=Independent: OK 2.5 生成 Step, Create Step: Procedure type=Static, General: Basic: Nlgeom=off 2.6 建立Load, Create Load: Step=Step-1 Mechanical=Concentrated force: CF1=1000 2.7 建立Bou ndary Condition， Create Boundary Condition: Step=Step-1 Mechanical=Displacement/Rotation: U1=0 U2=0 U3=0 UR1=0 UR2=0 UR3=0 2.8 建立Mesh，Mesh Type: Element Type=C3D20R 2.9 建立Job， Create Job: Name=Job-2 Model=Model-2: Submit 2.10 查看计算结果 Visualization: Plot Contours on Deformed Shape:U Magtinude
