Automated Structural Optimization System (ASTROS) Damage Tolerance Module. Volume 1 - Final Report
Abstract
This report is part of the documentation that describes the complete development of an SBIR Phase II effort titled, "An ASTROS Compatible Computational Strategy for Evaluating the Aeroelastic Response, Buckling, and Integrity of Composite A/C". This report is one of three manuals that comprise the final documentation. The remaining reports consist of a User's Manual, Volume II, and an Interface Design Document, Volume III. The Automated STRuctural Optimization System (ASTROS) is a multidisciplinary computer program for the preliminary design of aircraft and spacecraft structures. It integrates structures, aerodynamics, controls and optimization to make possible interdisciplinary design. This report describes The work performed to enhance the capability of ASTROS to perform preliminary design optimization of metallic and composite material aircraft, based on damage tolerance requirements. It defines the SBIR technical objectives and gives a technical description of the Damage Tolerance models. The Automated global-local analyzer, the Buckling analysis of a composite with/without delamination, the Finite Element Alternating Method, Fatigue crack growth and optimization are also discussed. Finally a short description of interfacing with ASTROS is given.
