Bookmark or Share- abaqus - solving penetration contact error between 2 surfaces - Eng-TipsPENETRATION 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 ...
- MAX. PENETRATION, MAX. CONTACT FORCE ERROR and NEGATIVE EIGENVALUES ...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 NEGATIVE EIGENVALUES." "MAX. PENETRATION ERROR 2.51836E-09 AT NODE SUPORTEPE-31-1.904 OF CONTACT PAIR (ASSEMBLY_S_SURF-822,ASSEMBLY_M ...
- pipe penetration on structural members - Eng-TipsAlso, plan for horizontal penetrations to be outside the compression block in sections with heavy flexural stress. Horizontal penetrations may interfere with longitudinal reinforcing placement, so look carefully at this. DO NOT attempt to relocate prestressing strand to avoid penetrations - move the penetration.
- Pipe Penetration Through Concrete Slab 3 - Eng-TipsWorking on a project where we are pulling our altitude valve and bypass line out of an underground pit at one of our elevated storage tank sites. We are relocating into an above ground building for better access. Building will be situated on a slab on grade. We will have a pipe penetration through the slab.
- Standard Penetration Tests: converting N values to densities 3 - Eng-TipsHi I am trying to design a retaining wall atm but I am having some problems as I can't find anyway to convert the N Values I have from borehole readings to densities. I am sure this really is very simple to do but I have unsucessfully searched the web and my core textbook, "Soil Mechanics...
