Schmidt-Ishlinskii Yield Criterion and a Rotating Cylinder with a Rigid Inclusion [PDF]
Journal of Applied and Computational Mechanics, 2021 An elastoplastic rotating cylinder with a rigid inclusion and fixed ends is investigated. The analysis is based on infinitesimal strain theory, Schmidt-Ishlinskii yield criterion, and its associated flow rule and perfectly plastic material behavior. Both

Anisotropic Antiplane Elastoplastic Problem [PDF]
Journal of Siberian Federal University. Mathematics & Physics, 2020 In this work we solve an anisotropic antiplane elastoplastic problem about stress state in a body weakened by a hole bounded by a piecewise-smooth contour. We give the conservation laws which allowed us to reduce calculations of stress components to a contour integral over the contour of the hole.

Biomechanical Analysis and Injury Prediction in Pilots With Lumbar Spondylolysis Under Different Seat Inclination Angles. [PDF]
JOR SpineThe biomechanical responses of three lumbar models under both seat angles remain below injury thresholds. However, the occurrence of spondylolysis at a 22° angle poses a higher risk. ABSTRACT Background This study aims to quantify the biomechanical effects of different seat inclinations on the normal and spondylolysis lumbar of pilots under typical ...

Elastoplasticity Informed Kolmogorov–Arnold Networks Using Chebyshev Polynomials
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Multilayer perceptron (MLP) networks are predominantly used to develop data‐driven constitutive models for granular materials. They offer a compelling alternative to traditional physics‐based constitutive models in predicting non‐linear responses of these materials, for example, elastoplasticity, under various loading conditions. To attain the

FEM-Based Compression Fracture Risk Assessment in Osteoporotic Lumbar Vertebra L1
Applied Sciences, 2019 This paper presents a finite element method (FEM)-based fracture risk assessment in patient-specific osteoporotic lumbar vertebra L1. The influence of osteoporosis is defined by variation of parameters such as thickness of the cortical shell, the bone ...
