Outline of Final Research Achievements

The appropriate measurement of stress distribution within the human body would provide valuable information to us. For the appropriate measurement to estimate stress distribution within the human body, numerical analysis is considered one of the most desirable methods. Since human body dimensions have individual differences, it is presumed that the way of the internal stress distribution also changes due to the differences. Thus, we developed human numerical models reproducing various types of the body forms and investigated the sleeping comfort of mattress by using human-mattress numerical models. From the results of numerical analyses, it is considered that sleeping comfort changes according to the differences of the body forms.
