Interfacial strength in thermoplastic composites - at last an industry friendly measurement method? [PDF]

open access: yes, 2002
Many elegant techniques have been developed for the quantification of composite micro-mechanical parameters in recent years. Unfortunately, most of these techniques have found little enthusiastic support in the industrial product development environment,

Experimental Study on Direct Tensile Properties of Cemented Paste Backfill

open access: yesFrontiers in Materials, 2022
Cemented paste backfill (CPB) has been increasingly utilized in mines for efficient mineral obtaining and regional ground support. To guarantee the work performance, the mechanical properties of CPB have long been a topic of study among researchers.

A technique for the measurement of reinforcement fibre tensile strength at sub-millimetre gauge lengths [PDF]

open access: yes, 2001
The strength of composite reinforcement fibres is normally measured on samples of much greater length than the actual residual fibre lengths found in many composite materials.

Bond Strength of composite CFRP reinforcing bars in timber [PDF]

open access: yes, 2015
The use of near-surface mounted (NSM) fibre-reinforced polymer (FRP) bars is an interesting method for increasing the shear and flexural strength of existing timber members.

A COMPARISON OF TESTING METHODS FOR DETERMINATION OF SPRAYED CONCRETE TENSILE STRENGTH

open access: yesActa Polytechnica CTU Proceedings, 2019
Sprayed concrete is important construction material in tunnelling. Primary lining is essential in NATM where the sprayed concrete can be loaded by tension due to bending moments.

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

Investigating the effects of loading rate and mixing design on concrete's direct tensile strength using the CTLC test [PDF]

open access: yesAnalytical and Numerical Methods in Mining Engineering
Tensile strength of concrete is measured using direct tensile tests on rectangular concrete samples with dimensions: 19 cm in length, 16 cm in width, 6 cm in thickness, and a central hole of 9 cm in diameter.

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.

Interfacial Bond Properties between Normal Strength Concrete and Epoxy Resin Concrete

open access: yesAdvances in Materials Science and Engineering, 2021
It is necessary to pay attention to the bonding strength of the interface between precast normal strength concrete (NSC) and cast-in-place epoxy resin concrete (EMR) when using EMR as a repair or filling material or an overlay in bridges’ rehabilitation.
