In-line dimensional inspection of warm-die forged revolution workpieces using 3D mesh reconstruction 

Mejia-Parra D.; Sánchez J.R.; Ruiz-Salguero O.; Alonso M.; Izaguirre A.; Gil E.; Palomar J.; Posada J. (Universitatea Politehnica Bucuresti, 2019-01-01)
Industrial dimensional assessment presents instances in which early control is exerted among "warm" (approx. 600 °C) pieces. Early control saves resources, as defective processes are timely stopped and corrected. Existing ...

A General Meta-graph Strategy for Shape Evolution under Mechanical Stress 

Montoya-Zapata D.; Acosta D.A.; Ruiz-Salguero O.; Posada J.; Sanchez-Londono D. (Taylor and Francis Inc., 2019-01-01)
The challenges that a shape or design stands are central in its evolution. In the particular domain of stress/strain challenges, existing approaches eliminate under-demanded neighborhoods from the shape, thus producing the ...

Density-sensitive implicit functions using sub-voxel sampling in additive manufacturing 

Montoya-Zapata D.; Moreno A.; Pareja-Corcho J.; Posada J.; Ruiz-Salguero O. (Multidisciplinary Digital Publishing Institute (MDPI), 2019-01-01)
In the context of lattice-based design and manufacturing, the problem of physical realization of density maps into lattices of a particular family is central. Density maps are prescribed by design optimization algorithms, ...

Geometry simplification of open-cell porous materials for elastic deformation FEA 

Cortés C.; Osorno M.; Uribe D.; Steeb H.; Ruiz-Salguero O.; Barandiarán I.; Flórez J. (SPRINGER, 2019-01-01)
Estimation of mechanical properties of porous materials is central for their medical and industrial application. However, the massive size of accurate boundary representations (B-Rep) of the foams makes the numerical ...

FE-simulations with a simplified model for open-cell porous materials: A Kelvin cell approach 

Montoya-Zapata D.; Cortés C.; Ruiz-Salguero O. (IOS Press, 2019-01-01)
In in-silico estimation of mechanical properties of open (Kelvin) cell porous materials, the geometrical model is intractable due to the large number of finite elements generated. Such a limitation impedes the study of ...

Quasi-isometric mesh parameterization using heat-based geodesics and poisson surface fills 

Mejia-Parra D.; Sánchez J.R.; Posada J.; Ruiz-Salguero O.; Cadavid C. (MDPI AG, 2019-01-01)
In the context of CAD, CAM, CAE, and reverse engineering, the problem of mesh parameterization is a central process. Mesh parameterization implies the computation of a bijective map ? from the original mesh M ? R3 to the ...

FEA Structural Optimization Based on Metagraphs 

Montoya-Zapata D.; Acosta D.A.; Ruiz-Salguero O.; Sanchez-Londono D. (Springer Verlag, 2019-01-01)
Evolutionary Structural Optimization (ESO) seeks to mimic the form in which nature designs shapes. This paper focuses on shape carving triggered by environmental stimuli. In this realm, existing algorithms delete under - ...
