Hello,
I am a Mechanical Engineer with a Masters from Indian Institute of Science Bangalore. I have been working in various fields of Mechanical Engineering: Product development of forging components and in software development of hyper-elastic finite element software development.
I am carrying out spring back analysis using LS-dyna and hyperform. The procedure as follows: forming is carried using LS-dyna and then the spring back is included in to the result file using hyperform and .k files are created using hyperform itself. While running the analysis, after certain number of iterations, the analysis aborts with message equilibrium can’t be achieved. I have included the both the input files (with and without spring back).
Please point out what could be the mistakes inthe input file and advice me for any additional inputs.
CAn any one explain me what is the difference between tension and tension-tension loadings....
Well I am really wondering about thsi right now as I read that I should really try to further my education via Distance learning .
hi
i am having problems solving two solid mechanics problems... can anyone please help??? the problems are:
Question 4:
A 2380 Nm torque is applied to gear D due to input torque from the motor at A, as shown in figure 4. Shafts 1 and 2 are both solid steel, 44 mm in diameter and 600 mm long. Gear B has a diameter of 250 mm and gear C has a diameter of 350 mm. The shear modulus G for steel is 80GN/m^2
Find out:
(a) the maximum stress in shaft 2
Hello,
I'm trying to simulate and compare principal stresses in model of bolt and nut, for different material data. I would like to get the soft/hard stage comparison. The problem is that I just do not know how to define hard stage material, it is not in standard material library in ansys (workbench or classic).
If anyone could help me giving some examples of hard stage materials data I would be greatfull.
Hi all,
I want to plot nominal stress Vs nominal strain plot from my FEA simulation. In generally I will get stress and strain at element level, now how can I plot stress-strain for the overall struture. I am applying uniaxual load on specimen. My analysis is non-linear.
Thank you
Regards
Gouse
