Analysis of the cup-cone fracture in a round tensile bar

Recognizing the critical need for standardization in strain imaging, in 2010, the European Association of Echocardiography (now the European Association of Cardiovascular Imaging, EACVI) and the American Society of Echocardiography (ASE) invited technical representatives from all interested vendors to participate in a concerted effort to reduce intervendor variability of strain measurement. As an initial product of the work of the EACVI/ASE/Industry initiative to standardize deformation imaging, we prepared this technical document which is intended to provide definitions, names, abbreviations, formulas, and procedures for calculation of physical quantities derived from speckle tracking echocardiography and thus create a common standard.

This review comprises a detailed survey of ongoing methodologies for soft actuators, highlighting approaches suitable for nanometer- to centimeter-scale robotic applications. Soft robots present a special design challenge in that their actuation and sensing mechanisms are often highly integrated with the robot body and overall functionality. When less than a centimeter, they belong to an even more special subcategory of robots or devices, in that they often lack on-board power, sensing, computation, and control. Soft, active materials are particularly well suited for this task, with a wide range of stimulants and a number of impressive examples, demonstrating large deformations, high motion complexities, and varied multifunctionality. Recent research includes both the development of new materials and composites, as well as novel implementations leveraging the unique properties of soft materials.

Some remarks on integration procedures for a viscoplastic constitutive law

Uniaxial and bi-axial tests on tubular specimens are presented. The specimens consist of NiTi alloy exhibiting pseudoelastic behavior at room temperature. A novel device to measure and control axial and torsional strains within a well defined gage section of the specimen was developed. This device, based on inductive transducers, uses the same reference points for both twist and elongation measurements. The viscous and rate dependent behavior of binary, pseudoelastic NiTi is investigated. The main focus is on the decoupling of thermal and viscous effects on the transformation stress as the specimen material is subject to heating and cooling due to latent heat generation and absorption during phase transition. On this account, an active temperature control is proposed to account for swift temperature variations. In addition to uniaxial testing of the sample, two-dimensional tension/torsion experiments are conducted in order to generalize the uniaxial findings. It is concluded that the material under consideration is independent of the rate of deformation for the applied temperature range.

Some remarks on rate-sensitivity of niti shape memory alloys

It is shown that objective rates of objective and symmetric second order Eulerian tensors should be corotational when one restricts to a single Euclidean vector space. As a consequence, when we equalize the objective strain rate and the deformation rate, only the Hencky strain is a mathematically consistent strain measure; and only the logarithmic rate is an admissible strain rate.

Comments on objective rates of 2nd order, symmetric Eulerian tensors

Constitutive relations which describe engineering materials behaviour during the finite elastoplastic deformations are usually presented in the form of rates of stresses and strains. One of the possible approaches in the constitutive relations formulation is the additive decomposition of the total deformation rate into its elastic part and its plastic part. The elastic deformation rate contributes to any elastoplastic deformation at any stage. Hence, its exact and well-considered formulation is of particular importance and it has to be properly predicted by the corresponding material law. This is of great importance in particular when deformation cyclic processes are considered, in which case small errors may accumulate, even if the total deformation is small. The implementation of the most frequently used corotational rates, i.e. the Jaumann rate and the Green-Naghdi rate, in the hypo-elastic constitutive relations regarding small and moderate rotations gives accurate results for low number of repeated deformation cycles. With increased number of cycles, however, the implementation of these rates results in different and physically non-admissible material responses. This instability in results is particularly observable during the cyclic deformations with large rotations, which is the main subject of this work. In contrast to the aforementioned objective rates, the results of the logarithmic rate implementation into the hypo-elastic constitutive relations for the case of pure elastic deformation describe a physically stable process.
