Optimal shells made of ideal anisotropic composites. ANSYS APDL codes and results for membrane shells
Description
The optimization problem investigates the shape and the fibers’ structure of membrane shells made of ideal anisotropic materials. The model of an ideal fibrous composite is the simplest model of a material comprised of high-modulus fibers and low-modulus matrix and is based on the following hypotheses: the fibers are distributed continuously in the matrix and they are inextensible, such that the loads are perceived just by the fibers while there are no stresses in the binder. Three archived datasets (ANISO5a.hyper1-L1.zip, ANISO5a.hyper2-L1.zip, ANISO5a.spher-L1.zip) are provided as the compressed files. In each ZIP-file there are the source codes in APDL-language, ANSYS-Classic database-format file and result file from ANSYS-Classic. The other files contain the ASCII-coded arrays for nodal coordinates and element parameters. All data from each ZIP-archive must be decompressed in the separate folder, one folder pro dataset. ANSYS APDL datasets contain three finite-element models for the optimal shapes momentless shells. Each ZIP-dataset includes APDL input codes, database files (.db) and results files (.rst). For the execution the Student version of commercial FE codes ANSYS is necessary. The datasets are considered as the additional software for the book project "Fundamentals of Structural Optimization (II)".. These calculations should help the reader to understand the analytical treatment of the optimization problems and perform simple verifications of analytical procedures with the numerical calculations.

Steps to reproduce
Possibility I. Calculations from scripted code: a) extract all files from each archive in a separate directory b) start ANSYS Classic APDL application (2022 and above, at least ANSYS-Student-Licensee) c) read the file "aashell.inp" from ANSYS application Possibility II. Restore *.db with the ANSYS-Classic application Possibility III. Read the results *.rst files with the ANSYS-Classic Application
