New lattice models for dynamic fracture problems of anisotropic materials
(Elsevier, 2019-05)
In this paper we present a two-dimensional lattice model to simulate dynamic fracture problems in anisotropic materials. The model is based on the equivalence of strain energy stored in a representative unit cell to its ...
A progressive damage based lattice model for dynamic fracture of composite materials
(Elsevier, 2020-11)
In this paper we present an extension of the linear elastic lattice model for anisotropic materials previously developed by the authors. This approach takes into consideration damage evolution in composite materials by ...
Dynamic seismic signatures of saturated porous rocks containing two orthogonal sets of fractures: Theory versus numerical simulations
(Oxford University Press, 2018-05)
The dispersion and attenuation of seismicwaves are potentially important attributes for the noninvasive detection and characterization of fracture networks. A primary mechanism for these phenomena is wave-induced fluid ...
Mechanical analysis of transversal iliac fracture stabilization using dynamic compression plate or screws and PMM in polyurethane bone model
(2017-01-01)
Pelvic fractures correspond to 20 to 30 % of the fractures observed in dogs. Complete fractures, especially with bone axis deviation should be surgically treated. The mechanical study of surgical techniques is of utmost ...
Synthesis Pengo System plates for the treatment of long-bone diaphyseal fractures in dogs
(Schattauer Gmbh-verlag Medizin Naturwissenschaften, 2008-01-01)
A Brazilian orthopaedic company designed a stainless steel plate called Synthesis Pengo System (S.P.S.), which has one fixed and one changeable extremity. According to the assembly of the changeable extremity, it is possible ...

Local Maximum Entropy Material Point Method applied to quasi-brittle fracture
(Pergamon-Elsevier Science Ltd, 2021-01)
This work aims to introduce an alternative technique to address the fracture process of brittle and quasi-brittle materials under the Material Point Method (MPM) framework. With this purpose the eigensoftening algorithm, ...
