Elliptic crack instead of line crack in Phase-field method

What should be the crack initial condition in phase field fracture simulation?

By using phi=0 (broken phase) for one line segment of nodes  crack can
be specified. but with the loading applied we expect some crack opening
displacement. now as there is only one node specifying both upper and
lower crack faces displacements +u and -u at that node will be zero. 

Any suggestions or ideas on how to simulate a drop test in abaqus?

Hello,

I am working on a research to simulate a drop test of a package box with ceramic saucer inside. I am not proficient in abaqus so I am looking for some suggestions.

Till now, I created a hollow box with 2 mm thickness to represent it as a cardboard box and a disc for a saucer. I have material properties for cardboard and saucer. Then I assembled the model in abaqus such that saucer is touching box at the bottom; this was initial condition.

Two PhD positions on computational and experimental multiscale mechanics at Eindhoven University of Technology, Netherlands

Our Mechanics of Materials Group at Eindhoven University of Technology, Netherlands has two openings for talented PhD students in the field of multiscale mechanics of materials. They are part of a European Union funded project on multiscale methods for advanced materials. One opening is onthe development of a fundamentally new multiscale approach towards material modelling and the other aims to integrate this approach with experimental methods.

Nonlinear free and forced vibration analysis of a single-walled carbon nanotube using shell model

 By :Payam SOLTANI, J SABERIAN, R BAHRAMIAN, A FARSHIDIANFAR

In this Paper, the nonlinear free and force vibration of a single-walled carbon nanotube (SWCNT) with simply supported ends is 

investigated based on von Karman’s geometric nonlinearity. The SWCNT described as an individual shell and the Donnell’s 

equations of cylindrical shells are used to obtain the governing equations. The Galerkin's procedure is used to discretized partial

Fixation and Mechanical Properties of Implanted Cartilage Replacements - Overview of three recently published papers

Partial- and
full-thickness cartilage lesions of the knee caused by trauma, disease or joint
instability are a common disorder affecting people of all ages. Implanted
cartilage replacements (ICR) have the potential to overcome the limitations of
conventional treatment methods and are a promising approach to restore
functionality of the joint. In spite of some success in engineering
cartilaginous tissue, inferior biomechanical and biochemical properties of ICR
compared to native articular cartilage (AC) and inadequate quality of fixation

Why mode shapes are not mass normalized when it is subjected to ambient excitation?

If the modal properties are obtained from ambient excitation, then the mode shapes will not be mass-normalized. what may be the reason ?

Postdoctoral research associate position in mechanics of materials, morphogenesis and biosinspired structures

One postdoctoral research associate position is available (dates negotiable). The successful candidate will work on one or multiples of the following topics: mechanics of morphogenesis in plants and 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. The candidate should have received (or expect to receive very soon) a Ph.D.
