- What is a full strength penetration weld? | Eng-Tips
Doesn't full penetration refer to a weld the full depth of the material being welded independant of strength? My interpretation is penetration is the distance your weld extends below the plate surface
- Roof Penetration detail through Metal Roof | Eng-Tips
Penetration-Free Attachment A first rule about any rooftop mounting is to do it without penetrating the roof membrane whenever possible While this may seem obvious, on metal roofs, it is often violated The norm for attaching things seems to be: "anchor to structure through the roof "
- MAX. PENETRATION, MAX. CONTACT FORCE ERROR and NEGATIVE EIGENVALUES . . .
Hello, I'm doing a simulation in abaqus standard and i wont to know if MAX PENETRATION, MAX CONTACT FORCE ERROR and NEGATIVE EIGENVALUES is a problem or i can stay with them? If yes, how can i fix them and how they afect my results Some exemples: "***WARNING: THE SYSTEM MATRIX HAS 23
- pipe penetration on structural members | Eng-Tips
Hi guys, I need to prepare pipe penetration (vertical and horizontal) details on structural members (beams, slabs, walls and staircase) Any reference that you can suggest? Is there any standard details that can be follow? E g , for beams, penetration is allowed at some distance from the
- CBR test - no reading at 0. 2 penetration | Eng-Tips
The test standard requires penetration to 0 2 inches and if the CBR at 0 2 in penetration is greater than the CBR at 0 1 in penetration the test shall be rerun I think what this means is you should not use the contrator to run your CBR tests and you should find an AMRL-approved laboratory to do the work f-d ¡papá gordo ain’t no madre flaca!
- abaqus - solving penetration contact error between 2 surfaces
PENETRATION ERROR TOO LARGE COMPARED TO DISPLACEMENT INCREMENT To solve I've tried the following: - lowering increments in Step to 1e-5 - I tried offsetting the one surface from the other (to try and stop penetration error?!) - changing the interaction properties definition from hard contact to linear contact, with stiffness 10,000 and set
- Steel Beam Penetrations (Sizes and detail?) | Eng-Tips
Fellow engineers, I am running into a problem in the field where beam penetrations through my steel beams need to occur Our detail shows that the depth of the penetration can be D 3 (D = depth of steel beam) and the length of the penetration is 3 4*D This rectangular penetration has fillet
- Contact problem - negative or zero pivot | Eng-Tips
Initial penetration is likely to cause convergence issues because it makes the determination of initial contact stiffness problematic However, it does not cause a zero- or negative-pivot error, this is mathematically impossible
