Theoretical and Applied Mechanics Letters, 2015 Under an applied voltage, dielectric elastomers (DEs) produce an actuation strain that is nonlinear, partly because of the material properties. In this study, an experimental characterization is conducted to evaluate how the ambient temperature and pre ...

Mechanical strength of tooth fragment reattachment
Journal of Biomedical Materials Research, 2001 The aim of this study was static and fatigue test investigation of the strength of a tooth fragment reattached with adhesives to the tooth body. Central bovine incisor teeth were used, and standardized fragments were obtained by cutting the incisal edge of the selected teeth.

Damage Mechanisms and Mechanical Properties of High-Strength Multiphase Steels [PDF]
Materials, 2018 The usage of high-strength steels for structural components and reinforcement parts is inevitable for modern car-body manufacture in reaching lightweight design as well as increasing passive safety. Depending on their microstructure these steels show differing damage mechanisms and various mechanical properties which cannot be classified ...

Twin-induced plasticity of an ECAP-processed TWIP steel [PDF]
, 2017 The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult.

Mechanical Strength of Stripped Optical Fiber [PDF]
, 2019 A novel removal technique of silica optical fiber coating with chemical stripping gel was used. We observed that the fiber strength decreases from 5.48 to 4.96 GPa in the case of tensile test and from 0.06 to 0.05 GPa in the case of bending test when the coating was removed from the cladding surface.
