Sizing and fit for swimsuits and diving suits 281

Fig. 10.26 Linear stretch analysis in dynamic position—arms spread across.

Additionally, it is possible to perform analysis of linear deformations of the suit on
the body. First, it is necessary to define linear measurements on suit pattern on which
the measurements will be taken. Measurements are first taken on suit unstressed, flat
2D pattern, after which the same position measurements are taken on the suit proto-
type simulated on a body model in static and dynamic conditions. From the differences
in linear dimensions, it is possible to calculate the percentage of material stretch and
compare the results with the elongation values obtained by real material measure-
ments in order to evaluate fit and functionality of computer prototype in dynamic
conditions.
Linear stretch analysis of simulated diving suit prototype on linear dimensions on
upper back body area, in position D2, is presented in Fig. 10.26. The figure shows the
differences between values measured in static and dynamic position, caused by the
arm movement. Diving suit requires a skin-tight fit, and elastic properties of neoprene
materials enable that fit but in a combination with precise construction and right scal-
ing of garment pattern to achieve the right pressure of the garment in static and func-
tionality in dynamic conditions. A stretch of neoprene material can be seen from the
differences between linear segment measurement on garment pattern and values mea-
sured on garment on the body in a static condition, Fig. 10.26.

10.6.2 Physical prototype testing

Verification of the whole diving suit computer-based design and development process
is, as usual, performed with the real physical prototype production, Fig. 10.27.
