An adaptive concurrent multiscale model for concrete based on coupling finite elements
(2018-01-01)
A new adaptive concurrent multiscale approach for modeling concrete that contemplates two well separated scales (represented by two different meshes) is proposed in this paper. The macroscale stress distribution is used ...
Estudo do efeito do processo de shot peening na taxa de propagação de trinca por fadiga na liga aeronáutica 2024 - T3
(Universidade Estadual Paulista (Unesp), 2015-01-20)
This work focuses to evaluate the effect of the shot peening process in the propagation rate of a fatigue crack already existing. The shot peening is a cold working process, which consists of repetitive blasting with steel ...

The relationship between pure delamination modes i and II on the crack growth rate process in cracked lap shear specimen (CLS) of 5 harness satin composites
(2015-11-10)
Carbon fiber reinforced polymers (CFRP) structure can include dropping-off plies in order to comply with design requirements aiming at significant weight savings. However this type of discontinuity represents a potential ...
Quantificação da incerteza do modelo randômico de Collipriest via metodologia Monte Carlo e "fast crack bounds"
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2020-11-24)
Mechanical structures are subjected to the cicles loads and collapse in fatigue conditions. There are many mathematical models describing the crack propagation. Generally, crack propagation models are classified by the ...
