EST method with GNU Octave

The EST method -- http://staff.ttu.ee/~alahe/ESThtml/ESTmethod.html -- is a general computational method, for solving boundary value problems for the structural analysis of frames, beams, and trusses. Differential equations are considered here together with a set of boundary conditions.  Compatibility equations for joint displacements and equilibrium equations for member end forces at joints serve as boundary conditions.

3D finite element modeling for instabilities in thin films on soft substrates

Spatial pattern formation in stiff thin films on compliant substrates is investigated based on a nonlinear 3D finite element model. Typical post-bifurcation patterns include 1D sinusoidal, checkerboard and herringbone shapes, with possible spatial modulations, boundary effects and localizations. The post-buckling behavior often leads to intricate response curves with several secondary bifurcations that were rarely studied and only in the case of periodic cells.

PhD positions in solid mechanics/biomechanics at Dartmouth College in 2015

I'm looking for prospective PhD students to study solid mechanics/biomechanics in 2015 at Dartmouth College (Thayer School of Engineering). Visiting or postdoctoral positions are also available for highly qualified candidates from fall 2015. The subjects of research include, but are not limited to, mechanics of morphogenesis in plants/embryos, fast motion of plants (e.g., the Venus flytrap's rapid closure), mechanical self-assembly and instability of thin structures (e.g., DNA, plant tendrils, self-assembly of nanostructures, etc.), and bioinspired structures.

Numerical analysis of quasi-static fracture in functionally graded materials

This work investigates the existing capabilities and limitations in numerical modeling of fracture problems in functionally graded materials (FGMs) by means of the well-known finite element code ABAQUS. Quasi-static crack initiation and growth in planar FGMs is evaluated. Computational results of fracture parameters are compared to experimental results and good agreement is obtained. The importance of the numerical fit of the elastic properties in the FE model is analyzed in depth by means of a sensitivity study and a novel method is presented.

Determination of stress intensity factor of FGM materials

It is important to note that the determination of Stress intensity Factors lead to major problem for researchers, some of them have proposed an analytical method based on linear fracture mechanic by using the theorem de Giffth and also Paris, other have proposed numerical method using finite elememt analysis codes such as Ansys or Abaqus, other researcher have used experimental method.
  However, these methods still need an improvement for given accurate results.
How to develop an analytical method and adopted to FGM structure.

Composite Manufacturing Process Modeling Using Poromechanics

Modeling and simulation of manufacturing of advanced composite material is a must in today's industry as the use of advance composites is increasing dramatically. The aim is to reduce the number of trial and error by development of a simulation tool to model and predict the manufacturing fundamental phenomena happening simultaneously in different scales. Poromechanics is a multidisciplinary and multiphysics concept which can be used to achieve this goal.

Stretchable and Transparent Hydrogels as Soft Conductors for Dielectric Elastomer Actuators

       A soft ionic conductor can serve as an artificial nerve in an artificial muscle. A polyacrylamide hydrogel is synthesized containing a hygroscopic salt, lithium chloride. Two layers of the hydrogel are used as ionic conductors to sandwich a dielectric elastomer and fabricate a highly stretchable and transparent actuator. When the two layers of the hydrogels are subject to a voltage, the actuator reduces its thickness and expands. An areal strain of 134% is demonstrated.

Journal Club: Overcoming Challenges in Mechanically Actuating Liquid-Crystalline Elastomers

Smart materials are designed to have a controlled response to external stimuli. Shape-memory polymers (SMPs) are one of the most well known classes of mechanically active smart materials and have experienced an incredible amount of research attention over the last decade. They are able to recover programmed deformations when heated above a thermal transition; however, are generally considered a one-time event. Liquid-crystalline elastomers (LCEs) are another class of actively moving polymers; however, these materials can demonstrate reversible and repeatable shape memory without the need for “re-programming” after each actuation cycle.
