The Layerwise Shell Theory is used to model discretely stiffened laminated composite plates and cylindrical shells for stress, vibration, pre-buckling and post-buckling analyses. The layerwise theory reduces a 3-D problem to a 2-D problem by expanding the 3-D displacement field as a function of a surface-wise 2-D displacement field and a 1-D interpolation polynomial through the shell thickness....

We construct, for the first time, an off-shell supersymmetric continuous spin gauge theory in 4-dimensional Minkowski spacetime, both constrained and unconstrained Lagrangian formulations. As extension to on-shell description [1], we employ auxiliary field close algebra of supersymmetry transformations off-shell. The 4d $\mathcal{N}=1$ massless supermultiplet is then denoted by $(\mathrm{\Phi},...

We report on new results in Witten’s cubic string field theory for the off-shell factor in the 4-tachyon amplitude that was not fully obtained explicitly before. This is achieved by completing the derivation of the Veneziano formula in the Moyal star formulation of Witten’s string field theory ~MSFT!. We also demonstrate a detailed agreement of MSFT with a number of on-shell and off-shell compu...
