ANALYSIS OF STRENGTH OF BRITTLE MATERIALS UNDER DIFFERENT STRAIN RATES USING LDEM SIMULATIONS

Autor: Luis Eduardo Kosteski, Chiara Valsecchi, Guilherme Schumacher Da Silva, Carla Driely Morsch Vidal

Publikováno v: Revista Sul-americana de Engenharia Estrutural. 17:40-59

This paper presents a study on the variation of strain rate influence with the scale effect in quasi-brittle materials. Works in the literature report an increase of dynamic resistance with strain rate. To study this relation, a numerical model that

Failure Surface Variation Obtained with the Truss-Like Discrete Element Method

Autor: Vicente Bergamini Puglia, Angelica Colpo, Luis Eduardo Kosteski, Guilherme Schumacher da Silva, Fabrício Goulart Fernandes

Publikováno v: Applied Mechanics and Materials. 784:225-232

This paper presents the study of failure surface obtained in the truss-like Discrete Element Method (DEM). The element constitutive law considers the fracture energy of the material and its spatial variation is used to take into account the heterogen
