Virtual test methods can contribute to reducing the great effort for physical tests in the development of lightweight products. The present work describes an approach for virtual testing of sandwich panel joints based on the Building Block Approach and the Finite Elements Method. Building on a multitude of physical tests on sandwich materials and joints, adequate sub-models are developed, validated and synthesized to top-level models. The developed approach is eventually applied for the development of a novel sandwich panel joint.

Download Characterization of Localized Failure Modes in Honeycomb Sandwich Panels Using Indentation Book in PDF, ePub and Kindle
The indentation behavior of aircraft floor panels (honeycomb sandwich structures) was investigated from the viewpoints of test methodology, effects of panel construction, and failure mechanisms. An indentation test method using a simply-supported plate was developed to replicate observed in-use failure modes. The localization and type of damage induced with this test method correlated extremely well with damage present in panels returned from airlines suggesting that highly-concentrated loads, such as from high heels, cause most panel damage. Furthermore, damage appeared to spread due to an accumulation of multiple damage events more so than propagating from only a few. Both aramid- and aluminum-cored panels showed failures that occurred just below the resin fillet on the top skin. Aramid failed in brittle compression and post-buckling whereas aluminum failed due to ductile buckling. These results strongly indicate that near-surface properties dominate indentation behavior in contrast to the core-dominated stabilized core compression test as well as the skin-dominated failure criteria used in ASTM-type impact tests. Indentation tests using various skin and core constructions demonstrated the influence of changing core density, core material, and skin construction as well as the synergistic effect of skin and core on indentation damage resistance. Several analytical models were examined to aid in understanding the failure mechanisms due to indentation. These suggest that large local skin deflections are important in local load redistribution leading to core failure.

Download Engineering and Testing of a Structual Joint for Honeycomb Panels in the VIP Completion Book in PDF, ePub and Kindle
Bachelor Thesis from the year 2014 in the subject Engineering - Aerospace Technology, grade: 1,3, Hamburg University of Applied Sciences, course: Sandwichstrukturen, language: English, abstract: With the proceeding technologies in full automatic CNC machines, this valuable resource raises the question whether panel pins are still the most effective way to build cabinets. Different ways for panel joints are discussed and a concept for a potentially more effective way will be elaborated and tested. In preparation for the engineering of a new panel joint, which would change the industry standard, design standards and guidelines for developing test coupons are analyzed and provided. Following the first designs of test coupons in the CAD system Solidworks is a company test to prove the strength for tension and shear loads. Furthermore, a value analysis will be created to prove the economic benefit of the developed joint. The progress of this research and development project will be shown based on testing for each stage of development and detailed analysis of failure modes with diagrams and pictures with the goal to achieve a more effective way of joining honeycomb panels.

Download Mechanics of Materials Book in PDF, ePub and Kindle
This book, framed in the processes of engineering analysis and design, presents concepts in mechanics of materials for students in two-year or four-year programs in engineering technology, architecture, and building construction; as well as for students in vocational schools and technical institutes. Using the principles and laws of mechanics, physics, and the fundamentals of engineering, Mechanics of Materials: An Introduction for Engineering Technology will help aspiring and practicing engineers and engineering technicians from across disciplines—mechanical, civil, chemical, and electrical—apply concepts of engineering mechanics for analysis and design of materials, structures, and machine components. The book is ideal for those seeking a rigorous, algebra/trigonometry-based text on the mechanics of materials.

The Fourth Conference on Fibrous Composites in Structural Design was a successor to the First-to-Third Conferences on Fibrous Composites in Flight Vehicle Design sponsored by the Air Force (First and Second Conferences, September 1973 and May 1974) and by NASA (Third Conference, November 1975) which were aimed at focusing national attention on flight vehicle applications of a new class of fiber reinforced materials, the advanced com posites, which afforded weight savings and other advantages which had not been previously available. The Fourth Conference, held at San Diego, California, 14-17 November 1978, was the fi rst of these conferences to be jointly sponsored by the Army, Navy and Ai r Force together with NASA, as well as being the first to give attention to non-aerospace applications of fiber reinforced composites. While the design technology for aerospace applications has reached a state of relative maturity, other areas of application such as mi litary bridging, flywheel energy storage systems, ship and surface vessel components and ground vehicle components are in an early stage of development, and it was an important objective to pinpoint where careful attention to structural design was needed in such applications to achfeve maximum structural performance payoff together with a high level of reliability and attractive economics.
