Hi Every one,



It is immense pleasure to meet all you in this technical forum.



I have a basic query in strength of materials



This is about of short beam



Beam dimensions are

L=7.375 mm

Dia =15.05 mm

Tip Force=27514 N



For the above beam, following are the geometrical properties



area=177.894 mm^2

IZZ=2518 mm^4

FEM error message

Submitted by youngyoon on

Hello,

I have been struggling with the following error message in FEMLAB software: "The length of fem.appl(1).equ.ind must equal the number of domains in the geometry." I don't know exactly how to fix this error message. Would you please help me?

 Thank you, Yoon

Electromechanical screw driven Tensile machine

I would like to know what is the role of data sampling, data capture rate and bandwidth in case of electromechanical static tensile test. What are their optimum values for a static tensile test of metals according to ASTM standards.

We are deciding to buy Instron 5567 series for 50kN. But we are unable to decide whether that high data acquisition rate, bandwidth is required. Please suggest.

Muskhelishvili's method of estimating USING COMPLEX POTENTIALS

Submitted by Ilias I. Tourl… on

I'm looking for resources for reading and studing concerning the Muskhelishvili's method of estimating the stresses and desplacement fields for singular states of stresses using complex potentials from given boundaries as they mentioned in Timoshenko's book 'theory of elasticity ' pages:203..209.

I tried in my school library and i found nothing.

Thanks in anycase

Viscoelasticity in Abaqus

Submitted by Andreas Burger on

Hi All,

 I would like to use Abaqus to model the viscoelastic material  behaviour of a polymer.



I have material data from a simple uniaxial creep experiment (nominal strain vs time).  I tried to use the viscoelastic material model in Abaqus.  I am a bit confused as to how I need to enter my data (what format). 

The manual says I have to specify the normalized bulk and normalized shear compliance . 

  


where is the shear compliance and the volumetric compliance
