Energy Flow Considerations for Structural Response under Blast

Abstract

Load-impulse (P-I) diagrams are commonly used for structural design and damage assessment. Recently, an energy-based alternative to P-I diagrams, known as Energy vs. Energy Rate (E-R) diagrams, was proposed. E-R diagrams are another tool for structural design and damage assessment from an energy flow perspective. This paper describes a study to assess and compare these two analytical approaches, and to provide examples for illustrating the findings.
