Tensile analysis and assessment of carbon and alloy steels using FE approach as an idealization of material fractures under collision and grounding

open access: yesCurved and Layered Structures, 2020
In this study, a numerical investigation tensile test using ANSYS on three different carbon and alloy sheets of steel: AISI 1030 medium carbon steel, AISI 1080 high carbon steel and high-strength low-alloy (HSLA) A606 steel, has been carried out.

Soft mechanical metamaterials with unusual swelling behavior and tunable stress-strain curves

open access: yesScience Advances, 2018
Soft mechanical metamaterials were designed to offer large negative/positive swelling ratios and tunable stress-strain curves. Soft adaptable materials that change their shapes, volumes, and properties in response to changes under ambient conditions have

Theoretical stress strain model for confined concrete

open access: yes, 1988
A stress‐strain model is developed for concrete subjected to uniaxial compressive loading and confined by transverse reinforcement. The concrete section may contain any general type of confining steel: either spiral or circular hoops; or rectangular ...

Behavior of Geopolymer Concrete Confined by Circular Hoops

open access: yesMATEC Web of Conferences, 2018
This paper discusses the behavior of geopolymer concrete subjected to passive confinement under compression loads. The confinement is induced by the use of lateral hoops, assembled from un-deformed reinforcing bars.
