How to realize the second boundary condition (Neumann boundary) in UEL of ABAQUS

Submitted by windy on

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

Submitted by Li Han on

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.

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.

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.

Dear all,


I would like to draw your attention to our recently published research on the simulation of high accuracy fracture growth:
