Ageing effects in the shear modulus of soils
(ELSEVIER SCI LTD, 2000)
Results of in situ tests of shear wave propagation are presented and analysed to evaluate the effects of geologic processes, stress history and ageing on the shear modulus of soils. These results show clear tendencies of ...
Study of the elastic shear modulus of Bio Bio sand using bender elements in an oedometer
(American Society Testing Materials, 2017)
The objective of the paper is to study the shear stiffness of Bio Bio sand. To this end, a system to measure the travel time of shear waves in Bio Bio sand samples using bender elements was designed and setup in an adapted ...
Roll wave prediction model of Herschel–Bulkley fluids evolving on porous bottom
(2021-09-01)
The media have been reporting natural disasters frequently associated with climate change. When it comes to mudflows, the impact is substantial, especially on highly vulnerable communities. Under appropriate conditions ...
The mechanical performance of concrete shear key for prefabricated structures
(Sage, 2020)
The mechanical performance of concrete connection plays an important role in the response of precast concrete structures. Unlike conventional small concrete shear key which is mainly to help with alignment at installation, ...
A simplified mathematical model to estimate the erosive capacity of a pulsating laminar muddy flow
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2018-09-01)
In this paper, we proposed and validated a simplified mathematical model to estimate the erosive capacity of a muddy laminar flow with roll waves (pulsating effect) on the free surface. From the perspective of applying ...
Shear wave propagation in residual soil–rigid inclusion mixtures
(Elsevier Science Sa, 2019-02)
Residual and tropical soils are particulate materialswith a wide range of particle sizes. Usually these geomaterials have a fine particle matrix containing dispersed rigid inclusions that affect theirmechanical behavior. ...
Escoamentos pulsantes com superfície livre: caracterização e sua ação em fundo de canais
(Universidade Estadual Paulista (Unesp), 2018-07-30)
No contexto de Desastres "Naturais", as corridas de lama têm sido objeto de estudo devido ao seu poder erosivo e, muitas vezes, destrutivo, acarretando perdas materiais vultosas e ceifando vidas. Nestes escoamentos, quando ...
