We recently proposed a method that uses distance fields to exactly impose boundary conditions in physics-informed neural networks (PINN). This contribution is available as an arXiv preprint.
Flexoelectricity is a universal property of all dielectrics by which they generate a voltage in response to an inhomogeneous deformation. One of the controversial issues in this field concerns the magnitude of flexoelectric coefficients measured experimentally, which greatly exceed theoretical estimates. Furthermore, there is a broad scatter amongst experimental measurements. The truncated pyramid compression method is one of the common setups to quantify flexoelectricity, the interpretation of which relies on simplified analytical equations to estimate strain gradients.
As part of the 1st Pan-American Congress on Computational Mechanics (April 27-29, 2015 in Buenos Aires, Argentina), Marino Arroyo and I are organizing a minisymposium - ``Smooth Approximations on Unstructured Nodal Discretizations: Finite Elements, Spline-based Techniques and Meshfree.'' The deadline for abstract submissions is November 20, 2014.
Research Studentship (PhD) in Computational Material Science: the topic is computational nano mechanics and concurrent multiscale methods for composites under impact loading.
I am currently implementing some meshfree methods in Matlab. I have already implemented the EFG method. Now I'm trying to implement the MLPG mixed collocation method, and here I run into a problem.
Hi All,
A minisymposium on Meshfree and Particle Methods will be organized for the International
Conference on Computational Methods (ICCM) 2010. ICCM 2010 will be organized and hosted by
College of Mechanical & Vehicle Engineering, Hunan University during November 19th-21st, 2010 in
Zhangjiajie, Hunan Province, China. Please check the ICCM 2010 website
http://dmvb.hnu.cn/ICCM2010 for more information about the conference and the venue.
