I want reaction and moments for a beam with varying cross section over length(taper beam). Creo can find for constant section(prismatic section). But My question is: Can Creo find moments/reactions for taper beam ? or Which software cam measure it ?
I try to answer your question. I don't think that Creo can't help to find those things (reactions and moments) even for the simplest beam. In fact that Creo can calculate static, dynamic, buckling, etc.
I suggest you to use MDSolid as the following document.
Creo has a different option for beam in Creo simulator. I checked it thoroughly. It solves for each kind of section, but it should be constant section. For the variable section, one has to use the conventional FEA, which doesn't give reactions in horizontal and vertical direction.
I would like to highlight that the example 4 provided in the document attached to Ariadne Tsambani answer leads to a coarse estimation of both displacements and internal reactions. In fact, the variation of the cross-section size leads to non trivial stress distributions and more complex constitutive relations. For more details on these aspects please see the attached document.
As a consequence, in my opinion, the best solution for an accurate analysis of a tapered beam is the use of 2D or 3D Finite Element software.
