Mathematical modeling of viscoelastic foam material for design of filtering respirators

The work is devoted to the development of a mathematical model foam material filtering half mask. analysis methods used study leveling negative effect compression pressure half-mask on soft tissues human face under conditions long-term operation was carried out. In order mutual influence in medium "filter - tissues", it proposed conduct virtual tests using numerical methods. models linear viscoelastic materials based relationship between input and output characteristics materials: stress strain. paper transfer function. designed investigate deformation
