PANDA2 is a computer program for the minimum weight design of stiffened, composite, flat or cylindrical, perfect or imperfect panels and shells subjected to multiple sets of combined in-plane loads, normal pressure, edge moments, and temperature. The panels can be locally postbuckled. Recent additions to PANDA2 include implementation of: 1. Sanders-type shell equations as a user-specified choice in addition to the Donnell equations; 2. a 'global' optimizer processor called 'SUPEROPT' which, in a single long run, finds optimum designs from several different starting designs; 3. Arbocz' extension of Koiter's special theory for computation of buckling load factors for perfect anisotropic cylindrical shells and knockdown factors for axisymmetrically imperfect shells; 4. capability to handle a new truss-core sandwich configuration, and 5. capability to handle isogrid-stiffened panels and shells. These extensions to PANDA2 are described and examples given.
