Measurement of interlaminar shear properties of pultruded CFRP composites based on modified DNS specimens

Case Studies in Construction Materials
A double-notch shear (DNS) test was modified for a measurement of interlaminar shear properties of pultruded carbon-fibre-reinforced polymer (CFRP) composites under moderate through-thickness compressive stresses, which were applied by torqued bolts.

Calibration of the Numerical Model of a Dynamic Replacement Column Formed Under Laboratory Conditions

Architecture, Civil Engineering, Environment
During dynamic replacement, the contractor has no direct control over the length of the column and its diameter. Therefore, field trial tests performed at the beginning of the work site are extremely important.

Understanding induced fracture instability based on the Mohr-Coulomb failure criterion

, 2018
This study aims to investigate the failure mechanism of rock fractures induced by excavation unloading and fluid injection in Singapore Bukit Timah granite. The experimental tests on unloading-induced and injection-induced fracture instability are conducted based on the shear-flow experiments. The tests on unloading-induced fracture instability consist
