Abstract

In view of drift occurs to positive impulse calculation by commonly used numerical integration method in engineering practice, stabilized numerical integration was proposed to calculate positive impulse. This method uses characteristics of stable system to effectively suppress drift of integration result. By comparing calculation results of FAE blast positive impulse, the result has been verified.

Key words： shockwave damage; positive impulse; numerical integration; transfer function
