Group,
I'm currently modeling a fluid storage tank that is under a pressure load. I'm having difficulties getting the applied pressure loads to be applied in the same direction for all of the surfaces. Some of the surfaces have the load vector pointing inwards on the tank and others are point...
I updated to Windows 8.1 a few weeks ago. I went to use my Inventor the other day and I get an application error on launch (error 0xc0000142). Anyone else having the same issue? AutoCAD still functions properly.
Can someone recommend this program for an online Masters program in Aerospace. I'm looking at the Aerospace Structures core program. Also, if you have experience with another online program please list that one here as well.
Thank you.
I need some assistance on where I could find an analysis method for cutouts in a fuselage. I need to add a small opening in the side of an Aluminum semi-monocoque fuselage. I'm not cutting any frames or stringers, just the fuselage skin boxed within the frames and stringers. I don't have any...
I'm getting back into the FEM world with a simple structural analysis undergoing acceleration loads. I thought the acceleration units were in inches/sec/sec (32.2"/sec/sec = 1g). However, when I apply the acceleration loads to the model, the freebody resultant loads are a factor of 12 greater...
Condition: I have a 7075-T6 part that has been shot peened. However, a local surface feature of the part needs to have .050" of material removed for assembly fit.
I don't know the shot peen process (i.e. type, intensity, etc.) of the current part needing the dimensional work.
My question is...
My question is concerning the method of calculating rivet bearing loads on the parent material for a countersunk rivet. First off, is it usually calculated or does the countersink make it not as critical as shear load? How is the contact area calculated for a machined, dimple, or double dimple...
I'm not a user of CATIA, but I'm requiring another company to supply me with an IGES output of a model that they developed for the purpose of CFD analysis. Is is possible for CATIA (all versions) to format the conditions of an IGES output so that the output is of NURBS curves (entity 126) and...
I'm working for a small company and we just had some skin panels chemically milled and they came back deformed (6" deflection over about 43" span). They were .12" thk 7075-T6 flat panels originally that were milled to .050" thk in large pocket regions on only one side for weight reduction...
I just received back a flat panel from our chemical milling facility and it is warped. The panel is 7075-T6 .080" thick aluminum alloy and measures 46"x24" roughly. The panel deflects almost 6" mid-span of the 46" length. The bow is in the direction of the chemical milled side. The chemical...
Is there online or CD/DVD video training on using NEiNastran Modeler and FEMAP? Schedule never seems to work out for classes taught down in Westminster.
Is there plug-in features for the Autodesk Inventor series just like SolidWorks?
Can someone direct me to how to create a hole pattern that is spaced a constant distant from a part's edge and the part's edge is a curved path? Thank you.
I a new NeiNastran user and also new to the FEA world and I might have a analysis job pending that would be dealing with phenolic honeycomb core, fiberglass skin panel sturcture contruction. I've done a search on the web and this site for honeycomb core topics on how to model (i.e. material...
First off, sorry for the posting of this question. I know the problem is very basic to the structural gods, but I've been out of the structure's loop for quite sometime now. I've been assigned a project (in protest) to fix a panel that has housed my circuit boards and other electrical gizmos...
Does Anyone know of an add-on or site that has Mil Spec hardware 3D model parts (i.e. fasteners, hydraulic fittings, etc.) for the Inventor modeling serires?
I'm trying to find a reliable resource for minimum bend radius for various materials. I'm currently working on a problem of a 2024-T3 formed sheet metal panel that is cracking at one of the panel edges. The panel isn't heavily loaded and it is in a relatively low vibration environment, so I...
I'm trying to estimate the force and dampening effect of an oleo strut on a piece of equipment. I need some guidance on what parameters I need to gather off the strut and then how to calculate the resistant force over the travel of the strut and the dampening the strut provides. I currently...
Does anyone know of a toolbox module, addon for SolidWorks that you could enter a AN/MS/NAS hardware part number and a part file is generated. I know there is the Smart Fastener function, but when you use a fastener from that toolbox the BOM part number is a generic fastener description and I...
