PROBLEM TO BE SOLVED: To provide a method of designing an viscoelasticity structure (mattress, cushion or the like) for supporting weight of a human being to relax the contact stress between the human body by using a computer. SOLUTION: In this method of designing the viscoelasticity structure for supporting weight of a human being to relax the contact stress between the human body by using a computer, a human model formed into a similar shape with a human body and modeled by limited elements is used. This method contains a process for analyzing the stress to be applied to the human model when the human model is brought in contact with the viscoelasticity structure modeled by the limited elements and for computing a target function by changing a design variable. With this design method, a mattress effective to prevent bedsores can be efficiently designed without repeating trial manufacture. COPYRIGHT: (C)2004,JPO
