Numerical Simulation of Shock Response and Dynamic Fracture of a Concrete Dam Subjected to Impact Load
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2016-01-01)
The shock response and dynamic fracture of concrete gravity dams under impact load are the key problems to evaluate the antiknock safety of the dam. This study aims at understanding the effects of impact shock on the elastic ...
Dynamic numerical analysis of the Mazar concrete faced rockfill dam in Ecuador – south america
(Springer, 2021)
The catastrophic effects of earthquakes that frequently hit the West coast of South America has motivated this research. The country of Ecuador, situated on the subduction border of the South American and Nazca tectonic ...
Análise sobre a Política Nacional de Segurança de Barragens com ênfase nos critérios de monitoramento/instrumentação
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia CivilUTFPR, 2021-08-27)
