Design methodology for structural silicone glazed curtain wall assembly has been well established for many decades with proven performance of building projects around the globe. At its core, the design methodology is based on the individual performance of the materials, and the assembly is designed using physical and geometric principles to perform within an expected load and deflection which usually are confirmed via experiential confirmation via mock-up assemblies. Structural silicone performance and allowable design stress is based on physical relationships of stress due to the strain of a proto-typical joint. There has been recent interest in exploring increased or modified design stress of sealants based on similar methodology. However, the challenge in the methodology is that silicone materials behave as hyperelastic elastomers which indicate that the relationship of stress versus strain is not linear and the materials behave with different moduli depending on the location of the allowable stress on the stress-strain curve. Using finite element models, the paper presents a comparative analysis of a structural silicone joint designed via the conventional hand calculation at different design loads. The analysis illustrates the higher potential stress peaks developed within the sealant during loading versus the expected stress from the conventional method of calculation. Frame deflection and glass thickness were also factored to understand the variables' impact to the distribution of stresses in the sealant joint compared to the original stress predicted from conventional methods of design. Methods to calibrate the actual material model used in the finite element software for hyperelastic materials are also presented. Physical assemblies were tested to compare the results of the software model, which also includes a modified test procedure to better understand the durability of the materials due to cyclical testing.

This thesis investigates the fracture of nearly incompressible hyperelastic media. It covers the different characteristics of bulk material failure under dilatational or distortional loads and develops a unified description of the corresponding failure surface. It proposes a coupled strain and energy failure criterion for the assessment of notch-induced crack nucleation and presents a weak-interface-model that allows for efficient stress, strain and failure analyses of hyperelastic adhesive lap joints. Theoretical concepts for the measurement of fracture properties of nonlinear elastic materials are provided. The methodology is developed using two exemplary hyperelastic silicones, DOWSIL 993 Structural Glazing Sealant and DOWSIL Transparent Structural Silicone Adhesive, and is validated using large sets of experiments of different loading conditions.

Joining techniques such as welding, brazing, riveting and screwing are used by industry all over the world on a daily basis. A further method of joining has also proven to be highly successful: adhesive bonding. Adhesive bonding technology has an extremely broad range of applications. And it is difficult to imagine a product - in the home, in industry, in transportation, or anywhere else for that matter - that does not use adhesives or sealants in some manner. The book focuses on the methodology used for fabricating and testing adhesive and bonded joint specimens. The text covers a wide range of test methods that are used in the field of adhesives, providing vital information for dealing with the range of adhesive properties that are of interest to the adhesive community. With contributions from many experts in the field, the entire breadth of industrial laboratory examples, utilizing different best practice techniques are discussed. The core concept of the book is to provide essential information vital for producing and characterizing adhesives and adhesively bonded joints.

Built upon the two original books by Mike Crisfield and their own lecture notes, renowned scientist René de Borst and his team offer a thoroughly updated yet condensed edition that retains and builds upon the excellent reputation and appeal amongst students and engineers alike for which Crisfield's first edition is acclaimed. Together with numerous additions and updates, the new authors have retained the core content of the original publication, while bringing an improved focus on new developments and ideas. This edition offers the latest insights in non-linear finite element technology, including non-linear solution strategies, computational plasticity, damage mechanics, time-dependent effects, hyperelasticity and large-strain elasto-plasticity. The authors' integrated and consistent style and unrivalled engineering approach assures this book's unique position within the computational mechanics literature. Key features: Combines the two previous volumes into one heavily revised text with obsolete material removed, an improved layout and updated references and notations Extensive new material on more recent developments in computational mechanics Easily readable, engineering oriented, with no more details in the main text than necessary to understand the concepts. Pseudo-code throughout makes the link between theory and algorithms, and the actual implementation. Accompanied by a website (www.wiley.com/go/deborst) with a Python code, based on the pseudo-code within the book and suitable for solving small-size problems. Non-linear Finite Element Analysis of Solids and Structures, 2nd Edition is an essential reference for practising engineers and researchers that can also be used as a text for undergraduate and graduate students within computational mechanics.
