Sardinia radio telescope finite element model updating by means of photogrammetric measurements

Submitted by Flavio Stochino on

 The 64 m diameter Sardinia Radio Telescope (SRT), located near Cagliari (Italy), is the world’s second largest fully steerable radio telescope with an active surface. Among its peculiarities is the capability of modifying the configuration of the primary mirror surface by means of electromechanical actuators. This capability enables, within a fixed range, balancing of the deformation caused by external loads. In this way, the difference between the ideal shape of the mirror (which maximizes its performance) and the actual surface can be reduced.

PhD in Biomaterials for Aerospace Composites

Submitted by Lee Margetts on

Applications are invited for a fully funded PhD studentship at the University of Manchester to help develop the next generation of simulation tools. These will be used to evaluate the structural integrity of novel aerospace composites under a wide range of operational conditions. The student will join a €3-4M euro research project that has recently been funded to investigate the use of biomaterials in aerospace composites. The project involves a range of academic and industrial partners in Europe and China, providing many opportunities for overseas research visits.

How to calculate Stress intensity factor through FE programming?

Submitted by mmalekan on

Dear all,

I need to calculate SIF through a FEM program by writing some line of codes. The problem is that I wasn't able to find a reference contains straightforward formulation and procedure for this. Can anybody help me please with this issue?

Cordially,

It gives me great pleasure to announce the outcome of the 2015 competition for the Eshelby Mechanics Award for Young Faculty. This award is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. The selection committee consisted of: K. Ravi-chandar (UT Austin), Huajian Gao (Brown University), G. Ravichandran (Caltech), Roger Fosdick (Minnesota University), and Yonggang Huang (Northwestern University).

 

PhD position in D. Rittel's group - OUTCOME collaborative project - ITN-ETN

Submitted by D.Rittel on

We are looking for a highly motivated individual with a strong background in materials science and mechanics, to sudy dynamic shear failure of metallic materials. Experience with numerical modeling required. Previous exposure to experimental work will be considered as an advantage.

Additional information can be found in the atatched description of the planned research.

Heat seal properties of polymer–aluminum–polymer composite films for application in pouch lithium-ion battery

Submitted by zhan-sheng guo on

Polymer–metal–polymer composite films are widely used in packaging, building, and cooling, and more recently as envelopes for pouch lithium-ion batteries (LIBs). The influences of heat seal temperature and dwell time on the heat seal strength (HSS) of five different multilayer films were investigated by T-peel testing. The failure modes were observed and analyzed by digital optical microscopy. Heat-sealing temperature and dwell time interacted and simultaneously influenced the HSS. Temperature was confirmed as the primary factor while dwell time was secondary.
