Isothermal and Adiabatic Stress-Strain Curves of Vulcanized Rubber

, 1939
The stress-strain diagram of rubber has been the subject of a large number of investigations, including those of Röntgen, Gough, and Joule in the nineteenth century, those on isothermal phenomena by Meyer and Ferri, and Wiegand and Snyder, and most ...

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.

Stress-strain curve of the tensile test.

, 2016
Three curves were chosen randomly from each of the three groups in this study. Ultimate stress of the sclera was lowest in the NCL group followed by the CL group and the control group; Ultimate strain (%) of the sclera was lowest in the CL group followed

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

Advanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Stress-Strain Curve of Fibrous Concrete in Compression

Journal of Zankoy Sulaimani - Part A, 2001
A simple experimental technique was used to obtain the stress-strain curves of the normal weight concrete containing steel fibers. An analytic expression for the stress-strain relationship of the normal weight fibrous concrete is developed. Equations to predict the ultimate strain and the block stress parameters of the fibrous concrete were developed ...

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

Advanced Engineering Materials, EarlyView.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

Tensile behavior of staple fiber yarns, part IV: experimental verification of predicted stress–strain curves

, 2017
In this paper, specific stress–strain curves were predicted for viscose, cotton, and polyester yarns spun by ring and rotor technologies. The average fiber-specific stress–strain curves were used to predict yarn-specific stress–strain curves.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Stress–strain curve prediction strategy based on instrumented indentation test using master curve of SS316 stress–strain curve

Nuclear Engineering and Technology
A full stress–strain (SS) curve is an important material property for characterizing mechanical behavior. It can be obtained directly from conventional uniaxial tensile tests. It can also be predicted from the load-displacement curve obtained from an instrumented indentation test (IIT). To predict the SS curves, the IIT can use iterative finite element

Evaluating Energy Absorption Performance of Filled Lattice Structures

Advanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...
