i am doing my research project on stability analysis of a cantilever rotating shaft-disk systems. i need to study some basic theory about this. please suggest me some books or publications. my email id is balaji.modepalli [at] gmail.com
hi my friends,
i am using abaqus standard Mohr-Coloumb plasticity to model uniaxial compression test, so i have sample and (upper and lower platen) to represent the compression machine , i apply the load through the movement of the upper platen, the stress strain diagram of my material is strain softening.

A methodology is devised to utilize the statistical mechanical entropy of an isolated, constrained atomistic system to define the dissipative driving-force and energetic fields in continuum thermomechanics. A thermodynamic model of dislocation mechanics is discussed. One outcome is a definition for the mesoscale back-stress tensor and the symmetric, polar dislocation density-dependent, Cauchy stress tensor from atomistic ingredients.

Dear Colleagues,
We would like to share our thoughts about our approach to Robust Design Optimization and our way how we sufficiently increase the speed of solution of RDO problems in full stochastic statement with the involvement of probability objectives and adaptive surrogate model construction tools.
We will present this theory during our joint Webinar with Ansys: The link to on-line Webinar registration…

Dear all Researchers,
I am writing regarding for the first time about the UAA(Unified analytical aspect) on Fatigue crack growth. The idea of this technique is this question : too many fatigue life prediction relations but still those are not perfect. on the other hand, new math ways still have not been the classical fracture mechanics. I am looking for some comments as response to this concern. Clearly, how we upgrade fracture mechanics theory using atomistic development in modeling fatigue propagation?
Let us talk about this.
Regards,

Dear all,
I have several questions about how to use existing constitutive law of material to code UMAT in Abaqus. I have carried out experiment for several powder materials, including metal, ceramic, polymer powders. The powder aggregate is compacted in a cylindrical die. After the compaction, relationships between axial stress and axial strain, radial stress and axial strain are obtained. The material under such condition is always treated as elastic plastic material.
Hello.all!
Is anyone doing the work on the modeling of constitutive equation of Grey cast iron in large deformation?
Recently i read Holm Altonbach's paper "on the Elastoplastic deformation of Grey cast iron" , i wonder how to convert the relation (stress-strain) into (stress-hardening parameter). I'm also not sure if the constitutive model can be used in large defomation simulation.
thanks in advance!
Y.T.
