Soil Fragmentation and Friability. Effects of Soil Water and Soil Management [PDF]

open access: yes, 2002
Soil fragmentation is a primary aim in most tillage operations in order to create a soil environment favourable for crop establishment and growth. Soils vary around the world from those exhibiting a self-mulching nature to those of a hardsetting nature ...

Mechanical properties of cement mortar with gamma-irradiated recycled plastic powder, pellet, and fiber

open access: yesResults in Engineering, 2023
This study aimed to investigate the impact of gamma irradiated recycled polyethylene terephthalate (PET) pellets, powder, and fibers on the mechanical performance and ductility of cementitious mortar.

Experimental studies of scale effects on shear strength, and deformation of rock joints [PDF]

open access: yes, 1980
The effect of scale on shear strength is studied by performing direct shear tests on different sized samples of large joints. A rubber moulding system is used to obtain impressions of the roughness from a variety of natural joint surfaces.

Tensile strength of a vegetated and partially saturated soil [PDF]

open access: yesE3S Web of Conferences, 2020
Vegetated soil’s shear strength has been usually assessed through direct shear tests and under triaxial compression stress paths while less is known about its behaviour under tensile stress.

Numerical study on tensile failures of heterogeneous rocks

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2020
Many experimental results have demonstrated the apparent discrepancy of a rock material between its flexural tensile strength measured using various bending methods and its tensile strength measured using direct tension method or Brazil disc (BD) method.

Mechanical Characterization of Cemented Paste Backfill

open access: yesEng, 2023
Mechanical characterization is important to the design and analysis of cemented paste backfill (CPB) structures. Unconfined compressive strength (UCS) tests have been widely used owing to their relative simplicity to characterize a material’s response to

Effect of Aspect Ratio in Direct Tensile Strength of Concrete [PDF]

open access: yesJournal of the Korea Concrete Institute, 2003
Although concrete members are not normally designed to resist direct tension, the knowledge of tensile strength is of value in estimating the cracking load. In general, there are three types of test method for tensile strength ; direct tension test, flexural tension test, and splitting tension test.

ORGANIC-RICH SHALE TENSILE STRENGTH MODELING [PDF]

open access: yes, 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.

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

open access: yesAdvanced 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

open access: yesAdvanced 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.
