280 Anthropometry, Apparel Sizing and Design

Determined pressure values showed differences depending if simulation was per-
formed on scanned or parametric body model. Significant differences are visible
on measurement points and body areas where the parametric body model does not
allow precise adjustment according to individual shape. This refers to measurement
points on the head, wrist, and ankles (CH, FH, ER, WR i IA). Pressure analysis of
the female suit also showed significant differences on measurement point CF between
scanned and customized body model, which can also be explained by the limitations of
parametric body model.
Result analysis showed better correlation between garment pressure values mea-
sured on scanned body models and real test subjects, which is mostly visible from
body areas where the parametric body model does not allow precise shape adjustment.
This refers to measurement points on the head, wrist, and ankles (CH, FH, ER, WR i
IA). Pressure analysis of the female suit also showed significant differences on mea-
surement point CF between scanned and customized body model, which can also be
explained by the limitations of parametric body model adjustment in the breast area.
Due to the limited possibilities of CAD system and inability for a fast and accurate
body animation of the parametric models, where there are only few predefined dynamic
postures accessible, the 3D simulation and computational analysis of stretching and
pressure in dynamic postures are performed only in a dynamic posture with arms spread
across. That dynamic posture reveals critical zone on the shoulder area, showing the
unwanted wrinkles that appear during the rising arm movement. Unwanted wrinkles
can be removed with additional corrections and modeling of curved segments in the
shoulder area. After corrections, stretch analysis of diving suit model on back, in a
dynamic position of arm spread across, showed satisfactory fit, Fig. 10.25.
