Abstract
This Masters' dissertation investigates the possibility of implementing the concept of inverse motion form finding in a commercial software. The inverse motion approach finds the initial, undeformed geometry of a design such that it obtains its desired design shape when service loads are exerted on the design. The implementation is limited to static mechanical loads on three-dimensional geometries.

A previously developed non-commercial code was used for verification of the implementation by comparison of nodal values. The implementation was deemed successful and thus the code could be used for further development.

Several examples of applications for the inverse motion form finding model are presented. The examples are simplified but... (More)

Popular Abstract
When an object is built using the exact dimensions of its desired geometry, the object may deform into an unwanted shape when a load is applied. However, the inverse motion form finding formulation can be used to calculate the manufacturing shape that will result in its desired geometry after a load is exerted on the object. This Masters dissertation investigates how to easily apply the inverse method through implementation in commercial software.
