The group of Advanced Materials and Dynamics Lab at the University of Arkansas at Little Rock has one opening for a Ph.D. student in the field of mechanics of materials. The appointment is starting on May 2014 or August 2014.

Consider the set of monic fourth-order real polynomials transformed so that the constant term is one. In the three-dimensional space of the coefficients describing this set, the domain of asymptotic stability is bounded by a surface with the Whitney umbrella singularity. The maximum of the real parts of the roots of these polynomials is globally minimized at the Swallowtail singular point of the discriminant surface of the set corresponding to a negative real root of multiplicity four.

Calorimetry is a widely used technique to study the thermal properties of materials including heat capacity, temperature and enthalpy of transformation/chemical reaction. In a typical calorimetry mesurement, a controlled power is supplied to the material to heat it up, and the resulting temperature as a function of time is recorded.

Dear all,

these papers might interest those engaged in the assessment of the mechanical properties of nanocomposites using multiscale approaches.

Enthusiastic and highly motivated postdoctoral scientists are sought to work on 3D printing/additive manufacturing at Singapore.  

The candidates should have rich experiences in relevant research areas, good publication records, and excellent writing skills.

Preference will be given to those with experience in (1) molecular dynamics modeling or (2) manufacturing. The contract will be one year and renewable subject to performance. 

The Swedish
17^th century Vasa ship is unique in its kind and of high cultural
and historical interest. Therefore, interdisciplinary research teams are
constantly busy to keep the slowly degrading and deforming warship in good
geometrical shape. Initiated in 2012, the latest research project aims to
investigate creep in the Vasa ship and to develop a new support system for
improved dimensional stability. For this purpose a finite element model will be
created to assess the effect of varying geometrical parameters and material
properties. One of the key aspects is the influence of the joints of the ship

Dear all,

This paper might interest those engaged in the assessment of non-linear notch root stresses and strains. Please take a look, the paper is free.
