Abstract

Abstract

Lung blast injury is the most common cause of death from primary blast injuries, and effective protection is crucial for mitigating injuries and improving treatment outcomes. Research on polyurea materials as body armor is still in its early stages. This study conducted numerical simulations to investigate the mechanical response of lungs protected by polyurea under blast wave conditions and the attenuation characteristics of polyurea against blast waves. LS-DYNA was used to simulate the direct damage process of blast waves on the thorax of goats wearing protective materials, and the validity was verified through field pressure data and gross lung injury observations. Finally, the finite element model of blast wave protection effects was used to evaluate the protective effects of polyurea materials on human lung blast injuries. The results showed that when the right lung faces the blast center, the stress from lung injuries is mainly concentrated in the lower lobe of the right lung. The overall stress in the protected lung model is lower, and the lung overtraction effect caused by the negative pressure is weakened. Polyurea materials can effectively attenuate the peak overpressure on the skin and lung surface by approximately 58.8%, reduce the maximum velocity of the sternum by about 22.4%, and enhance attenuation capacity with increasing blast wave pressure, thereby effectively reducing the incidence and severity of lung blast injuries. The established computer simulation evaluation model for personnel protection effects provides a method for evaluating the protective efficacy of new protective materials against lung blast injuries and predicting post-protection injury severity, with significant military and social implications.
