Latest progresses on the phase field model for brittle fracture
Dear Fracture mechanician,
In my group we published 2 articles with novelties on the phase field model for brittle fracture:

How to upgrade an older Universal Testing Machine?
A Universal Testing Machine Retrofit is a system upgrade in which the capabilities and functionality of an outdated and/or broken universal testing machine are improved by pairing them with advanced indicators and replacement components. A system retrofit is commonly performed on but not limited to tensile testing systems, compression testing systems, torsion testing systems, and bend testing systems. Universal testing systems manufactured by Instron, Satec, MTS, Tinius Olsen, Baldwin, Forney, and others are all capable of being upgraded by ADMET’s retrofit service.

Post Doc in Mechanics of Polymer Foaming
Polymers are commonly foamed in the solid phase by the expansion of a dissolved gas such as CO2. The foaming process is sensitive to the constitutive properties of the polymer, and the final porosity is dictated by bursting of the cell walls. There is a need to model the solid foaming process for a range of polymers in order to determine the sensitivity of foaming to the properties of the polymer and to the process variables (such as thermal history and CO2 content). The foam expansion response is sensitive to the constitutive properties of the polymer.
Engineer: Career Pathway Conundrum – job or business
Dear all,
I am seeking some insights from professionals in any field to guide me and help me decide where to focus.
I have done masters in aeronautical and mechanical engineering and I have 5 years of experience in the field of design and development. From an Australian point of view, I am an experienced mechanical design engineer/mechanical designer.
Failure of brittle materials using simple experiments -Part 1
Below is the video link to my first lecture video, where in I tried to demonstrate the failure of brittle materials using simple experiments.

the new impact factor for JAM
The 2016 impact factor for Journal of Applied Mechanics has increased to 2.133. This increase is mainly due to the rapid review process, which has led to significant increase of submissions (and significant decrease of the acceptance rate). The average time for the first round of review is < 10 days, and that for the second round of review (if necessary), including both the authors' revision time and reviewers' re-review time, is < 3 weeks.
Recent Work "Modeling the Energy Storage and Structural Evolution during Finite Viscoplastic Deformation of Glassy Polymers"
The enthalpic response of amorphous polymers depends strongly on their thermal and deformation history. Annealing just below the glass transition temperature (Tg) causes a large endothermic overshoot of the isobaric heat capacity at Tg as measured by differential scanning calorimetry, while plastic deformation (cold work) can erase this overshoot and create an exothermic undershoot. This indicates that a strong coupling exists between the polymer structure, thermal response and mechanical deformation.
