Pressure garments are functional garments designed for medical purposes and arc normally used under prolonged stress. The stress across seams is related to the size of the wearer and the fit and the garment, the more close fitting a garment, the greater stress is put on the seam. Since pressure garments are subjected to appreciable stress during wear, seams with the required strength and extensiblity are particular *** seam type, stitch type, stitch density and thread strength are the main factors determining the strength and extensibility of a seam. In this paper, investigation of seam strength and extensibility are made on four types of seams which have been used for making pressure garments. Five different types of stitch densities and two sizes of sewing thread are used on each type of scam to be tested. The seaming conditions of the selected fabric are also examined.

The problems with traditional finite element program (FEP) can be solved by object oriented programming (OOP). This paper describes the application of OOP to finite element programming. The classes of object oriented FEP are given, and several class hierarhies are illustrated. The features of object oriented languages such as inheritance, encapsulation, and ploymorphism are fully applied in the FEP developed by the authors. Compared with the traditional FEP (usually in Fortran), our object oriented FEP in Borland C++ is more structured, more easily to be written, maintained and expanded. An outstanding feature of our FEP is that it can include not only displacement type elements but also hybrid stress elements. To demonstrate reusability and extensibility on the object oriented FEP, examples of adding new types of elements are given.
