Maria and I are doing our project on the contact of a sphere under force on a rigid surface. We will be studying the existing theoretical equations that model this effect, particularly the Hertz contact equations. We will then model this system on abaqus and illustrate that the theoretical results match the analytical results. The resulting deformation of the sphere when pressed onto the rigid surface will be the parameter of the most interest here.
I'm trying to implement the standard linear solid (Maxwell form) in ABAQUS. I can't find anything on how the 3 constants of the SLS model get input into ABAQUS in terms of the g_i's, k_i's, and tau_i's ABAQUS uses. For example, in a relaxation test, the modulus is given by Y(t) = C_1 + C_2*exp(-C_2*t/C_3), where the C_i's are the constants. I don't know if the standard linear solid makes any assumptions about deviatoric vs dilatational behavior. Does anyone know how to do this? -Thanks, Roman
Kathleen DiSanto and I are interested in finding out what the displacemnet distribution is for an elastic sphere contacting a ridgid surface. This Problem has many applications in sports such as golf and baseball, where the golf club and the baseball bat can be seen as ridgid materials compared to the elastic golf ball or baseball.
My project will be a literature study on ferroelasticity and how it applied to how of the topics we covered in class.

launches Mimics 11.1, the new release of the company’s medical imaging and
editing software. This new release builds on the last one, enhancing export to
FEA even more. Overall usability and performance were improved with some very
nice new features. Take a look at our website for more information.
Stress/Strain Analysis of Bullet-Holeson the Boeing 737 Fuselage Boeing 737 is the most popular aircraft in the sky today, with each one taking off or landing on average of every 6 seconds. One of the most important analyses conducted on these passenger aircrafts is determining the impact of any damage on the fuselage.
Overview. This post is a description of the project Sunny Wicks and I will be pursuing for this class, to satisfy the requirements for Problem 29.
Hii All
i am using 20 noded brick elements with reduced integration to analyse stress and displcement fields in a simply supported beam. how can i control hourglassing effect? please give me suggestions.

Professor Vlassak mentioned that last year every single person did a finite element project. He said he wanted to see more theory projects, so I decided to take him up on that.
I was browsing around one day and happened upon an article that explained that while the Green's function of the laplacian was positive definite, the biharmonic operator's Green's function is not. Physically, this has significance.
