Finite volume analysis of reinforced concrete structure cracking using a thermo-plastic-damage model [PDF]

open access: yes, 2019
This paper proposes modifications to the phenomenological model formulation called CDPM2, developed by Grassl et al. [1]. The proposed modifications are designed to enhance model performance with coupling to temperature effects.

Strength evaluation of flake and spheroidal graphite cast irons using diametral compression test

open access: yesJournal of Materials Research and Technology, 2017
The diametral compression test also known as the Brazilian test is an old and unique method of measuring tensile strength of brittle materials owing to simple specimen geometry test conditions and quickness of testing.

Energy Band Alignment and Electro‐Optical Behavior of Nearly Unstrained Monolayer MoS2 Heterostructures With GaN

open access: yesAdvanced Materials Interfaces, EarlyView.
Large size (∼100 µm) monolayer MoS2 grown by LPI‐CVD on n‐GaN exhibit a high n‐type doping, very low strain, and a type‐I band alignment at MoS2/GaN interface. Photocurrent measurements under illumination with photon energies from ∼2 to ∼5 eV show superior electro‐optical performances of these MoS2/n‐GaN heterojunctions as compared to Ni/n‐GaN devices ...

New Multistage Sheet-Bulk Metal Forming Process Using Oscillating Tools

open access: yesMetals, 2020
A new sheet-bulk metal forming process for the production of bulk components out of a flat sheet has been developed. Superimposed oscillation has been applied to the new process. By this means, process limits regarding better mould filling were expanded,

A strain tunable single-layer MoS2 photodetector

open access: yes, 2019
Strain engineering, which aims to tune the bandgap of a semiconductor by the application of strain, has emerged as an interesting way to control the electrical and optical properties of two-dimensional (2D) materials.

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...
