Duration: 47 min
SUMMARY
SCI is developing a bespoke software (EMBlast) for predicting accurately, fast and simplistically the loading on buildings caused by energetic materials.
The methodology of EMBlast is based on the Low-Altitude Multiple Burst (LAMB) shock combination rules, complemented with a large number of experimental tests and numerical analyses. LAMB is a semi-empirical approach, initially developed for nuclear detonations, that provides a reasonably accurate method for combining incident and reflected airblast shocks from high-explosive detonations of energetic materials. The experimental results and the numerical simulations assist in validating the LAMB predictions and also assist in expanding the range over which the LAMB method can be applied. Data is key to developing, extending and validating the software. Therefore, a collaboration has been established with the University of Sheffield, where its test site at Buxton will be used to perform medium scale explosion tests.
This webinar introduces EMBlast and presents its latest soon to be released module that provides blast pressure time-histories on target surfaces from external explosions.
