Book Description
This thesis outlines the development of a two custom CubeSat structures used for the DESCENT mission. DESCENT aims to test the feasibility of Electrodynamic Tethers (EDT) to deorbit spacecrafts. The payloads and bus components require DESCENT to have its own custom structures. The design is initially completed using a Computer Aided Design (CAD) software to create a solid model that fulfills the requirements stated by the launch provider. Next, a Computer Aided Engineering (CAE) tool is then used to create a Finite Element Model (FEM) of the satellites. The FEM is then used to run a Finite Element Analysis (FEA) to validate the structural integrity of the satellites in the launch and thermal environments. After the structure had been validated, technical drawings of components were completed, and the parts were manufactured. Finally, the manufactured parts were assembled together, and a fit check was completed to confirm the satellites outer dimensions.

Book Description
Designing satellite structures poses an ongoing challenge as the interaction between analysis, experimental testing, and manufacturing phases is underdeveloped. Finite Element Analysis for Satellite Structures: Applications to Their Design, Manufacture and Testing explains the theoretical and practical knowledge needed to perform design of satellite structures. By layering detailed practical discussions with fully developed examples, Finite Element Analysis for Satellite Structures: Applications to Their Design, Manufacture and Testing provides the missing link between theory and implementation. Computational examples cover all the major aspects of advanced analysis; including modal analysis, harmonic analysis, mechanical and thermal fatigue analysis using finite element method. Test cases are included to support explanations an a range of different manufacturing simulation techniques are described from riveting to shot peening to material cutting. Mechanical design of a satellites structures are covered in three steps: analysis step under design loads, experimental testing to verify design, and manufacturing. Stress engineers, lecturers, researchers and students will find Finite Element Analysis for Satellite Structures: Applications to Their Design, Manufacture and Testing a key guide on with practical instruction on applying manufacturing simulations to improve their design and reduce project cost, how to prepare static and dynamic test specifications, and how to use finite element method to investigate in more details any component that may fail during testing.

Book Description
Bachelor Thesis from the year 2014 in the subject Engineering - Aerospace Technology, grade: 10/10, Universidad Europea de Madrid, language: English, abstract: The whole Cubesat functionality depends on the integrity of its subsystems. For that reason, it is very important that the structure subsystem is built to be robust and reliable to ensure the protection of all other subsystems integrated within. The goal is to develop a high performance Cubesat structure with the use of new materials, like composite materials. The use of composite materials for primary structure increases the strength and reduces the weight of existing Cubesat structures increasing at the same time the payload capacity. Interplanetary missions require more robust and reliable structures so a Cubesat manufactured with composite materials could be the solution for those exploratory missions. One of the keys of a composite structure is the design in order to reduce manufacturing cost and stress concentration, especially on interference with other components. The results of study on alternative structures designs for Cubesat, shows that one solid wall composite Cubesat design can stand up to 25g loads with a temperature range of -55°C (-67° F) to 90°C (194° F). Additionally, the vibration simulation results show a minimum vibration mode of 157.6 Hz. All of that was achieved with a weight of 183 grams.

Book Description
In Finite Element Design of Concrete Structures: practical problems and their solutions the author addresses this blind belief in computer results by offering a useful critique that important details are overlooked due to the flood of information from the output of computer calculations. Indeed, errors in the numerical model may lead in extreme cases to structural failures as the collapse of the so-called Sleipner platform has demonstrated.

Book Description
A wing structural layout design experiment conducted with a commercial aircraft manufacturer indicates that a systematic, evolutionary structural design process helps to focus integrated discussion analysis and decision-making efforts The process systematically incorporates optimized structural information into the design process The technical complexity of aircraft design requires technically skilled individuals to communicate disciplinary needs to people outside of their own disciplines Tools and methods that help interdisciplinary information transfer and can evolve with the fidelity required by the design process will improve a design organization's capability to produce an integrated aircraft that meets all of design requirements This paper shows that advanced structural design tools, used in a multidisciplinary team setting will improve structural information generation and communication This will enable a design team to better identify and meet structural design requirements. A realistic example demonstrates how high fidelity computational structural tools can generate and communicate structural information appropriate to the process needs. This means that the information is actually used to make decisions.
