Hi, all
I'm working on a structural optimization problem invovled with running numiercal analysis with Abaqus. Therefore, it is impossible for us to use the direct differentiation method to calculate the sensitivity of design variable. But I guess there should a way to get sensitivity analysis done numerically with Abaqus. Anyone know such information or give me a short instruction on that, I would highly appreciate!
Best Regards,

We're pleased to announce a collaboration with MachineWorks' Polygonica for our future software releases. The collaboration involves adding Polygonica's mesh processing libraries into our +CAD module, which extends our core 3D image processing platform ScanIP.
Hi my friends!
I hope everythin's ok!
As I previously said I'm doing some researches about fully developed turbulent flow inside an annuli.Now I've faced some problems. Does anyone know how can I calculate Darcy friction factor for a fully developed turbulent regime inside an annuli not using colebrook equations and moody diagram? is there any other way?
I'd be really thankful if anyone could help me .

In numerical simulation of sheet metal
forming process, the cyclic mechanical behavior of metallic sheet is
required to calibrate the material parameters of the combined
isotropic-kinematic hardening model. Therefore the development of
experimental device and method is an important work in order to
measure the cyclic mechanical behavior of metallic sheet. There are
several experimental devices which can measure this cyclic mechanical
behavior of sheet metal mainly to measure the Bauschinger behavior.
Often, these experiments can be classified into three main
categories: (i) in-plane tension-compression test; (ii) in-plane
cyclic simple shear test; (iii) bending-reverse bending test.
In this paper, a novel approach is

Hello everyone,
I want to reproduce global buckling of a 3D column (simply supported) using shell elements independently of its length.
I know that each section of the column should behave like a rigid body but I can't do it, so by doing the buckling analysis I get other buckling modes (like local buckling).
My initial idea was to use rigid body (tie) constraint in some sections (uniformly spaced) but what I got was some local buckling in the extremities of the column.
Recently, the classical view of DNA as an isotropic elastic rod has been questioned. Here we model DNA as an elastic rod inlaid with fibrils, based on which we have made prediction that is in consistency with experiments. Our analysis suggests that the bending of short DNAs can be facilitated if there exists a specific structural heterogeneity.
