The Noise Control and Acoustics Division (NCAD) is sponsoring the 2017 Symposium on Phononic Crystals and Metamaterials.  This symposium, which will be in its 13^th year, will feature presentations covering all aspects of phononic crystals and acoustic/elastic/phononic metamaterials.

Deadline for Abstract Submission: March 6, 2017

Conference Website: https://www.asme.org/events/imece

 Call for Abstracts attached.

This is a 9 months post-doc position on modelling crack problems at Portsmouth University (UK). 

The project will focus on using Abaqus to model the full field near-tip strains. Corresponding experimental data has been collected for model validation using Digital Image Correlation. Deadline for application: 12th March 2017. International applicants welcome. More details and instructions to apply on: http://www.jobs.ac.uk/job/AXH079/senior-research-associate-in-fracture-…

The Indian Space Research Organization (ISRO) has funded a 2 year project to BITS Pilani (Goa and Hyderabad campuses). The simulation project will model atomistic fracture in amorphous silica, with application to the Thermal Protection System (TPS) of the Reusable Launch Vehicle (RLV).

Details of application are mentioned in the attachment.

Dear colleagues,

These notes are a part of the notes on linear algebra.

In lecture, I have been using this google doc, which contains more tables.

In general we use Johnson-Cook model for bullet, which accounts for strain-rate effects, while for the target (Composites), the we use orthotropic constitutive model. Does it mean that strain-rate effects are not important for composites? The Johnson-Cook model cannot be readily used for composites. How does the AUTODYN considers strain rate effects for composites in ballistic impact simulations?
