Development of computational methods and conduct of experimental tests for blast loading analysis J.E. Slater," D.V. Ritzel" & P.A. Thibault& "Defence Research Establishment Suffield, f .O. Avenue S.E., Medicine Hat, Alberta, Canada, TM (9B5 ABSTRACT Sample results from an extensive series of experimental air-blast loading tests are presented to illustrate load enhancement due to shock interaction and focussing, which can result in unexpectedly higher peak blast pressure and impulse loading on exposed structures. An advanced computa- tional fluid dynamics (CFD) method that has been developed and integrated with a Graphical User Interface (GUI) on a UNIX-based workstation for blast analysis is discussed. To illustrate the capabilities of the Blast Analysis Worksta- tion, results are presented and correlated with test data. INTRODUCTION Determination of air-blast loading, whether from weapon or accidental explosion, is of major interest to the mili-
