ABSTRACT
For the sake of simplicity, we use the terminology “generalised displacements” to represent both potential field and displacement fields, and “generalised stresses” to represent both potential flux and elastic stresses (see Figure 4.1). In consequence, most variables can be commonly used in both potential and plane elastic problems.
4.2 Input and output Although input of necessary data and output of final computational results for any program are technically less demanding aspects, they are important to practical engineers. It is well known that preparation of data and interpretation of intermediate results in running a computer program are generally time-consuming in engineering analysis. Therefore, input and output subroutines are essential components in any computer program used for engineering computation. This section presents both input and output subroutines which can be used in either potential or plane elastic problems.
