PhD Scholarship Available at USQ Australia

Submitted by Xuesen Zeng on Wed, 09/06/2017 - 05:10

Research Topic – Manufacture of Aerospace Structures using Automated Fibre Placement.

Carbon Fibre Reinforced Plastic (CFRP) composites are being used increasingly in the load-bearing structure of aerospace vehicles. Automation is vital for better productivity of these large structures. This project will lead to the establishment of a state-of-the-art automated fibre placement (AFP) research capability at the Centre for Future Materials (CFM). This project will be key to ensuring the success and future growth of the aerospace sector in Queensland and Australia.

phase field modeling

Several Ph.D. student positions are available in phase field and mesoscale plasticity areas at Purdue University’s School of Materials Engineering. In addition to meeting all admission requirements, the ideal student would be one who is theory and computations oriented, with background in Fortran 90 and/or C++ skills and reasonable knowledge in mechanics and microstructure science of materials. Students with M.S. degree in mechanical engineering/mechanics, aerospace engineering/mechanics or in materials modeling and simulations are desirable for these position. To start in January 2018, a prospective domestic student needs to apply by the middle of October and an international student by October 1, 2017. For inquiry, please send email to Professor Anter El-Azab (aelazab [at] purdue.edu).

Journal Club for September 2017: Some recent developments in constitutive modeling of glassy polymers

The physics of glassy materials is a fascinating area of research. On one hand, the statistical mechanics understanding of their behavior is an active and exciting area of research. On the other hand, it is still quite challenging to develop and calibrate predictive constitutive models that reproduce all the observed behaviors. Many of the physical aspects the thermo-mechanics and ageing behavior of glasses are what actually make their constitutive modeling complex.

A Hybrid Multi-Scale Model of Crystal Plasticity for Handling Stress Concentrations

Submitted by Ali Ramazani on Mon, 09/04/2017 - 17:48

Microstructural effects become important at regions of stress concentrators such as notches,
cracks and contact surfaces. A multiscale model is presented that efficiently captures microstructural
details at such critical regions. The approach is based on a multiresolution mesh that includes an
explicit microstructure representation at critical regions where stresses are localized. At regions farther
away from the stress concentration, a reduced order model that statistically captures the effect of the

#-D Modelling of COmposite Laminates

Hi,

While modeling laminated composites we use their material properties (stiffness matrix) to compute the ABD matrix. When E_z of the core is much higher than E_x and E_y, how can we model such a plate using 2D FEM?

Understanding the strength of bioinspired soft composites

Submitted by Konstantin Volokh on Sun, 09/03/2017 - 09:23

Remarkable mechanical properties of biocomposites (bone, teeth, shell, antler etc.) are usually attributed to their special design where staggered mineral platelets are embedded in a protein matrix. Because of the high aspect ratio of the platelet the soft protein deforms in the shear mode predominantly providing the linkage for the hard inclusions. Mimicking Nature one might design materials with a similar architecture.
