Chip formation in thermomechanical simulation of metal cutting


I am simulating thermomechanical model in Abaqus. I am not able to get chip out. I have used shear deformation criterion. Is there any key step to achieve this?

Also I am facing problem with coupled thermomechanical CPE4RT element. I am using Dynamic explicit thermal displacement step. In this step I didn't find adiabatic heating option, Abaqus is giving me warning about it. What are the necessary inputs for this simulation.

Please answer if anybody knows about this.

Rheology is the science of deformation.  This science poses a question for every material:  Given a history of stress, how do we predict the history of strain, or the other way around?

On the stress singularities generated by anisotropic eigenstrains and the hydrostatic stress due to annular inhomogeneities

The problems of singularity formation and hydrostatic stress created by an inhomogeneity with eigenstrain in an incompressible isotropic hyperelastic material are considered. For both a spherical ball and a cylindrical bar with a radially-symmetric distribution of finite possibly anisotropic eigenstrains, we show that the anisotropy of these eigenstrains at the center (the center of the sphere or the axis of the cylinder) controls the stress singularity.

Geometric nonlinear thermoelasticity and the time evolution of thermal stresses

In this paper we formulate a geometric theory of nonlinear thermoelasticity that can be used to calculate the time evolution of the temperature and thermal stress fields in a nonlinear elastic body. In particular, this formulation can be used to calculate residual thermal stresses. In this theory the material manifold (natural stress-free configuration of the body) is a Riemannian manifold with a temperature-dependent metric. Evolution of the geometry of the material manifold is governed by a generalized heat equation.

Elastic leak of a seal

Our paper in the new journal Extreme Mechanics Letter has come online:  An elastomeric seal may leak by elastic deformation without any material damage. We describe elastic leak using a theoretical model, and watch a seal deform and leak using a transparent experimental setup. The elastomer seals the fluid by forming contact with surrounding hard materials. As the fluid pressure increases, the contact stress also increases but not as much.

Fiber-reinforced tough hydrogels

Our paper has appeared in EML (Extreme Mechanics Letters) and can be downloaded.  Using strong fibers to reinforce a hydrogel is highly desirable but difficult. Such a composite would combine the attributes of a solid that provides strength and a liquid that transports matter. Most hydrogels, however, are brittle, allowing the fibers to cut through the hydrogel when the composite is loaded. Here we circumvent this problem by using a recently developed tough hydrogel.

Journal Club Theme of December 2014: Neuromechanics

Descartes said: `I think, therefore I am’. Darwin wrote, ‘I think’. Unarguably, the brain is the most complex and mysterious part of our body that has intrigued both scientists and philosophers alike for centuries. It is the seat of our sensory perception, emotions, learning, memory, and consciousness. While the role of electrochemistry in the working of the brain and these processes have been investigated extensively in the last century, the role of mechanics or mechanical stimuli in controlling the structure and function of the brain has remained essentially elusive.

PhD Scholarship in the Mechanics of Materials

A fully funded PhD scholarship exists in the area of mechnics of materials, endowed in honour of Professor M F Ashby.  The successful applicant will have a 1st class degree (and ideally a Masters degree) in an appropriate field.  The precise topic of the PhD can be fixed after the scholarship has been awarded.  Further details may be obtained from Ms H A Gardner.

PhD Studentship in Mechanics of Lightweight Structural Protection

Fully funded 3 year PhD in the Mechanics of Lightweight Structural Protection.  The project is an experimental and theoretical investigation of the invention of lightweight energy absorbing materials under static and dynamic loading.  The challenge is to optimise the use of multi-layers to contain a projectile or fragment in a lightweight panel, by exploring the use of metal lattices and composites. The project requires a 1st class honours degree or equivalent in engineering, applied science or materials science.


The School of Materials Science and Engineering (SMSE), Xi’an Jiaotong University (XJTU), invites applications for multiple new faculty positions (assistant professor, associate professor and professor). As a “211” and “985” school, XJTU is a one of the top universities in China, with a dynamic research atmosphere.
