Dynamic testing of the elastic modulus and shear modulus of full-scale laminated veneer lumber [PDF]

BioResources, 2021
The feasibility of the dynamic testing was explored for the elastic modulus and shear modulus of full-scale laminated veneer lumber in batches at the production site. In order to do so, dynamic testing and analysis, involving a hammer blow and detection of frequencies, were carried out on the laminated veneer lumber free-plate placed in two ways ...

Investigation on the dynamic shear modulus of fiber-reinforced sand

IOP Conference Series: Earth and Environmental Science, 2021
Abstract As a new type of composite material, fiber-reinforced soil has attracted much attention due to its good dispersibility, mechanical properties and durability. Based on the dynamic triaxial test, the dynamic characteristics of polypropylene fiber-reinforced sand were studied, and the effects of fiber content (w), fiber length (lf
