Sorry All. For the delay response from my side. I have listed what I was done earlier and Now I have done sample calculation in the attached presentation.
As @LiftDivergence mentioned method can be used only one calculation if require, but in my case I have to do this for around 122 locations...
I am not doing the in-service repair. I am creating the SRM manual using the existing repair task. Where in my case, I am using trying Lightening strike repair, where I have change the rivets, due to that the clamping factor has been changed from previous revision. My previous calculation was...
@Stress_Eng Thanks for your calculation. But the assumption you made is Fir and applied stress in Tangent modulus calculations are same which looks ok initially to me. The allowable IRB value also looking ok to me. However, in the second page you created one graph with the relation of Fir vs Et...
@rb192 the load distribution is between intercostal and skin. I don't have the picture right now, I will share it once I got it. I am not clear about their load distribution method, since I am doing a repair analysis for the part which already analyzed. I will discuss those with the person who...
@LiftDivergence , @rb192 Thanks for your replies.
@rb192 The load has been extracted from the grid point of FEM (Analyzing component is Intercostal which is idealized as Tria shell element). The formula used here to calculate at outer flange stress as (Fx/A+MzY/I) As mentioned this...
Hi,
I am currently doing the inter rivet buckling analysis. The formula which I am using from Bruhn chapter C7.14 which suggest me to use tangent modulus. My applied stress at the current location is -357MPa, where as my material Fcy is 290MPa. If I try to find the Tangent modulus using...
