Tensile Testing, Second Edition is a comprehensive guide to the uniaxial tensile test and its use in determining the mechanical properties and behaviors of materials. The first six chapters cover the fundamentals of tensile testing, including the methodology, the equipment used, the effect of tensile loading on metals, the interpretation of data, and the role of tensile testing in design and manufacturing. The next six chapters deal with the testing of different classes of engineering materials, namely metals, plastics, elastomers, ceramics, and composites, and fabricated structures such as weldments and bolted and adhesively bonded joints. The book also includes three chapters on the nuances of tensile testing at extreme temperatures and strain rates and a reference section with data tables.

In the context of automotive crash simulation, rate-dependent properties are sought for all materials undergoing deformation. Measuring rate-dependent properties of adhesively bonded joints is a challenging and associated with additional cost. This article assesses the need for having rate-dependent properties of adhesively bonded joints for the example of a typical automotive structure, an adhesively bonded metallic T-joint. Using Finite Element simulation it could be shown that good agreement between experiment and simulation was only achieved if rate-dependent properties were considered for the adhesive.

Abstract A good understanding of the process of adhesion from the mechanics viewpoint and the predictive capability for structural failures associated with adhesively bonded joints require a realistic modeling (both constitutive and kinematic) of the constituent materials. The present investigation deals with the development of an Updated Lagrangian formulation and the associated finite element analysis of adhesively bonded joints. The formulation accounts for the geometric nonlinearity of the adherends and the nonlinear viscoelastic behavior of the adhesive. Sample numerical problems are presented to show the stress and strain distributions in bonded joints.
