Hi, I'm trying to model a blast load on a 1.2x0.7 m section and 6.8m height well reinforced column in ls-dyna. I used a blast load of 300kg TNT at 30 m but the response of the column was very low. Since 300kg is a considerable amount of TNT weight (possibly more than a car bomb) is this response...
I'm modeling a explosion in a air domain (eular) I want to set the boundaries to be non reflectory. When I tried I could not select the outer faces of the eular mesh to be impedence boundary. So how the define the outer surfaces of a eular domain as non reflecting surface
Thank you

Hello everyone,
I'm trying to model a concrete member subjected to a blast load. When the model is analysed is shows very high hourglass energy, But when I try to reduce hourglass by using ELFORM 2, -1, -2 some nodes get negative volumes. How could this be resolved
Thank you
Can any one please tell me how to get the length of steel rebar specimen required to test the tensile strength according to ASTM A370. I cant get my hands on the code. therefore please help
Can anyone please provide me some reference for designing of precast beams. I lack the precast background therefore wish to start from the simple basics. An attachment would be very helpful. Thank you
In past literature it keeps on mentioning about exterior and interior precast beam-column connections. Can anyone please explain the difference of these two. Also can anyone attach most commonly used precast column-beam connection detailed drawings if possible. Thank you
