Dear all,
i'm reading the new ASME 2007 sec VIII div 2 code and i'm facing some problems with the elastic-plastic stress analysis.
In particular, chapter 5.5.4 describes two method to perform fatigue calculation in an elastic-plastic stress analysis: the "cycle-by-cycle analysis" and the...
In a manufacturing chain, Macro-scale residual stresses are introduced in a speciman by heat treatment, welding or other manufacturing process occuring before machining.
These residual stresses are self-equilibrated before starting material layers removal in machining. When material has been...
Dear all,
I need to check stresses in a wood milling machine. I search on my books but I've data only for steel as milled material.
I'd use the following formula to compute tangential forces acting in the milling cutter:
FT = ksm * (va/(z*n)) * sqrt(p/D) * B
where
va: cutter/piece advancing...
Dear All,
can someone explain me the theoretical difference between an HARMONIC RESPONSE ANALYSIS and a SPECTRUM ANALYSIS?
I'm going to analyse a piping system subject to acoustic inducted forces, given to me in Force-vs-frequency form.
Thanks again,
Michelebold
I'm doing a structural verification of a piping system.
Is it correct to check for allowable stresses in separeted cases: deadweight+prssure nad thermal loads?
I mean: i've checked if maximum stress intensity is under the allowable stress for deadweight+pressure and than in a separate analysis...
Dear all,
i'm analysing the flexibility of a petrolchemical plant using ansys piping capabilities. The model includes some vessels connected by piping systems. I've modeled the vessel and the pipes with PIPE16 and PIPE18 elements. My problem is how to simulate the beams connecting the axis of...
Dear all,
I must perform a piping stress analysis in order to evaluate the ground reactions and the nozzle forces in a complete piping model. I'l use ANSYS. Someone can indicate me some tutorials or guides to learn how to model my piping system? There's any examples to benchmark my procedures...
dear collegues,
i cannot understand if internal pressure can influence steel pipe natural frequencies.
i've modeled a steel pipe in ansys using PIPE16 elements and solid elements. I've fixed supported both the models in one end. For each model, i've made two simulation: with and without...
