Dear Colleagues
The condensed version of Advanced Mechanics of Materials book in now posted on my web page for you to review. You can go directly to it using this link. I welcome comments, suggestions, and corrections.
How to realize the second boundary condition (Neumann boundary) in UEL of ABAQUS
There are higher-order deformation gradients in the higher-order deformation theory, in which higher-order stresses are usually involvded in order to meet conjugating principle. In that way ,higher-order stress boundary conditions (such as Neumanm boundary ) should be applied when solving the partial differential eqution.
I want to know how to apply this second boundary in UEL of ABAQUS.
any help and suggestions are greatly appreciated.
Modulating crack propagation in a multilayer stack with a super-layer
Quantitative characterization of interface adhesion and fracture properties of thin film materials is of fundamental and technological interests in modern technologies. Sandwich beam specimens used in fracture mechanics techniques, such as four-point bending and double-cantilever beam have been widely adopted, including the semiconductor industry.
Simpleware case study: 3D FE Model of the Diabetic Neuropathic Foot
Diabetic foot represents a complication of diabetes that can lead to foot ulcers and other serious conditions. 3D Finite Element (FE) analysis enables dynamic characterisation of different loads within the foot.
This study developed a subject-specific 3D FE model of a diabetic neuropathic and a healthy subject’s foot from MRI data. Experimental analysis of the biomechanics of the foot was combined with FE simulations of foot models generated in Simpleware software.
WEBINAR - Introducing 3Dlab and New Features for Multi-Disciplinary Optimization in TURBOdesign Suite 6 | 30th September
TURBOdesign Suite is a unique aerodynamic and hydrodynamic 3D design software package that allows users to design, analyze and optimize all types of turbomachinery, such as axial, mixed-flow, or centrifugal pumps, compressors, fans, turbines and torque converters.
Constructive and Destructive Interplay between Piezoelectricity and Flexoelectricity in Flexural Sensors and Actuators
Flexoelectricity is an electromechanical effect coupling polarization to strain gradients. It fundamentally differs from piezoelectricity because of its size-dependence and symmetry. Flexoelectricity is generally perceived as a small effect noticeable only at the nanoscale. Since ferroelectric ceramics have a particularly high flexoelectric coefficient, however, it may play a significant role as piezoelectric transducers shrink to the sub-micrometer scale. We examine this issue with a continuum model self-consistently treating piezo- and flexoelectricity.
EMI 2016 & PMC 2016 Conferences
The event to be held on May 22-25, 2016 at Vanderbilt University in Nashville, Tennessee, is actually two co-located conferences: the Engineering Mechanics Institute Conference 2016 (EMI 2016) and the Probabilistic Mechanics & Reliability Conference 2016 (PMC 2016). The event will be chaired by Prof. Sankaran Mahadevan and Prof. Caglar Oskay, both of Vanderbilt University.
create shell planar in 2D model ? (Abaqus 6.13)
Hi,
I have modeling a ground in abaqus and simulated earthquake. will i need allow infinite elements in the laterals model (left and right). In other examples i see in the features (module part) created "shell planar" en the places to create the infinite element (edge, no plane)... so .. how its made ?
thanks.
PD: Me english is terrible, sorry.
