Towards a material damage model using the logarithmic strain, with von Mises plasticity considerations
Damage is briefly defined as the presence and growth of micro-defects in a material. This study serves to describe the computational implementation of the material damage theory adopted for ductile materials. Thus, pays attention to the computational analysis of the physical behaviour of materials …

Probabilistic Machine Learning for Circular Statistics: Models and inference using the Multivariate Generalised von Mises distribution
… we introduce the multivariate Generalised von Mises distribution (mGvM), which allows the use of kernels in circular statistics akin to Gaussian Processes, and an augmented representation. These models account for a vast number of applications comprising both latent variable modelling and …

La figure d'autrice : mises en scène de soi et réception des écrits intimes de Claire Martin, Marie Uguay et Nelly Arcan
… Nelly Arcan. Ces trois écrivaines, en raison des mises en scène de soi dans leurs écrits intimes, ont connu une réception critique conditionnée par un horizon d’attente genré. Se resserrant autour de six œuvres (Dans un gant de fer [1965], La joue droite [1966], Journal [1980], Putain [2001], …

A Finite Element Study of Stresses in Stepped Splined Shafts, and Partially Splined Shafts Under Bending, Torsion, and Combined Loadings
The maximum von Mises stress is calculated for solid finite element models of splined shafts with straight-sided teeth. One spline shaft is stepped with larger diameter section containing spline teeth and the smaller diameter section circular and cylindrical with no spline teeth. A second shaft is …

Asymptotic theory for Bayesian nonparametric procedures in inverse problems
… of this thesis, we investigate Bernstein--von Mises type results for adaptive nonparametric Bayesian procedures in both the Gaussian white noise model and the mildly ill-posed inverse setting. The Bernstein--von Mises theorem details the asymptotic behaviour of the posterior distribution and …

Development of Surrogate Model for FEM Error Prediction using Deep Learning
… mesh. For this research, we have taken the von Mises stress contours and have predicted two different types of error indicators contours, namely (i) von Mises error indicator (MISESERI), and (ii) energy density error indicator (ENDENERI). Error indicators are designed to identify the solution …

Rank-based Two Sample Tests Under a General Alternative
… are closely related to the two-sample Cramer-von Mises criterion. The first one is a linear transformation of Cramer-von Mises criterion in the case the two samples are of the same size. The second one is a different form of the Cramer-von Mises criterion. The properties of the two-sample test …

Bayesian dynamic borrowing strategies with power priors and quantifying prior information for circular priors.
… are measurements on a unit circle, with the von Mises model being the most widely used model for such data. We gauge the information contained in priors for the von Mises data model using prior equivalent sample size.

Chebyshev spectral method for incompressible viscous flow with boundary layer control via suction or blowing
The MISES quasi 3-D design/analysis code implements a two-equation integral method with empirical closure relations to solve the boundary layer flow problem with or without suction, but lacks the option of flow control via blowing. The integral method is parameterized with the shape parameter H _ …

Plasticity and impact test studies on thermoplastic materials, finite element analysis and experimental correlation
… elasto-plastic models based on the Von Mises yield criteria, but also to check the influence of different simulation variables. The parameters studied were the element type, mesh density, friction and contact conditions between different parts. Additionally, another yielding criteria, …

Investigation of Small Remotely Piloted Aircraft System (sRPAS) to Human Head Impact
… head injury-related responses such as skull von Mises stress, brain strain, and strain-based cumulative strain damage measure (CSDM). HIC showed moderate to strong correlations with skull stress. BrIC correlated with brain strains but at weaker correlations compared to the correlations in other …

Elastic-Damaging Plasticity Model for Ductile Fracture
… employs continuum damage mechanics and a von Mises plasticity model. The elastic-damaging model is based on the assumption that damage occurs due only to hydrostatic tension, and this, combined with the von Mises plasticity model, allows a simple formulation of the proposed model. Parameters …

Aerodynamic design of an aspirated counter-rotating compressor

Influence of Hexagonal Height on the Stress Distribution

Non-Linear Finite Element Method Simulation and Modeling of the Cold and Hot Rolling Processes
