ORGANIC-RICH SHALE TENSILE STRENGTH MODELING [PDF]

, 2016
Shale mechanical characterization is an expensive and time intensive lab and field exercise. Experimental observations in lab shale characterization have shown some relation (linear or non-linear) between fracture toughness and tensile strength.

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Tensile Properties of Jute-Polypropylene Composites

Chemical Engineering Transactions, 2018
This paper describes the tensile behaviour of jute-polypropylene fibre composites with different fibre volume fractions. Here, the composite laminates consisting of weaving jute fibres, with the fibre volume percent in the range of 20 to 80 % and polypropylene plies were prepared using hand lamination.

Tensile properties of orthodontic elastomeric chains [PDF]

The European Journal of Orthodontics, 2004
The purpose of this investigation was to assess the permanent elongation, tensile strength and toughness of elastomeric chains. Two types (open and closed chains, i.e. with and without an intermodular link) of three brands of elastomeric module yielding six groups were included in the study.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
