Anomalous behavior of structural elements under the action of blast loads

Characterization of asymmetrical beam instability to impulsive load

“…The symmetrical instability has attracted many researchers since 1980s (Symonds and Yu, 1985;Forrestal et al, 1994;Galiev and Nechitailo, 1986;Galiev, 1996Galiev, , 1997Galiev et al, 1997;Kolsky et al, 1991;Li et al, 1991). Some simplified Shanley-type models have been developed to characterize the beam symmetrical instability which is called a counter-intuitive phenomenon (Symonds and Yu, 1985;Genna and Symonds, 1987;Symonds et al, 1986;.…”
