Experimental methodology of study of damage initiation and development in textile composites in uniaxial tensile test [PDF]

, 2008
Damage in textile composites is closely connected with the internal micro- and meso-geometry of the reinforcement, and reveals features, which are not present in the damage processes in classical laminates. This paper proposes a test sequence intended to

Experimental Study of the Dynamic Characteristics of PVA-Amended Expansive Soils

Applied Sciences, 2023
Expansive soils are distributed across a wide area in China, and land transport and surface construction will inevitably involve these soils. To mitigate the deficiencies of single-method expansive soil modification, it is highly important to adopt the ...
