Introduction

ShapeBuilder can generate complex beam cross-sections using the component definition approach. In that approach, the cross-section comprises various interconnected structural components. The adhesive connection joins two structural components along a line. When manufacturing rotor blades, structural components are often bonded together using a thin layer of adhesive material; the “adhesive connection” performs the same task for the ShapeBuilder model.

Figure 1 illustrates the role of the adhesive connection. Two structural components, denoted ComponentA and ComponentB in the figure, are joined together along a line. A number of nodes, represented by red circles, are defined along edge A1 A2; similarly, a number of nodes, represented by red crosses, are defined along edge B1 B2. In general, the number of nodes along the two edges and their locations differ. The adhesive connection establishes constraints between the two sets of nodes. The connected nodes share identical degrees of freedom.

Notes

  1. To define an adhesive connection, use @CONNECTION_TYPE: AHDESIVE
  2. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
