Converting the abundant energy from the sun into a form convenient for human use has been a long standing dream for sustainable generation of environmentally clean energy.  With the seminal discovery of water splitting by Fujishima and Honda in the early 1970s [1], titanium dioxide (TiO2), an inexpensive white pigment widely used in our daily life, emerged as the premier photocatalysts for enabling solar energy utilization. However, because of its wide intrinsic band gap, TiO2 can absorb only ultraviolet light. This results in less than 1% efficiency for solar energy conversion. Reducing the band gap of TiO2 is the main avenue for boosting the conversion efficiency. In a recent paper to appear in Phys Rev. Lett. [2], Zhu et

Dear All

 Currently I am working as a researcher and there is a new project on which i need some help. I have to do a contact analysis between two bodies initially and than move to low speed impact betrween two composite materials. I have just started using Abaqus and not very familiar with it. I have although completed some very basic application like cantilver beam and stress analysis, but struggling to complete a contact analysis between two bodies in a simple 2D problem.

As the title suggests, there are two focuses of this discussion theme: impact and cellular materials.

Impact protection can be very practical problems in safety, fires and explosions, oil and gas industry, subsea structures, car manufacturing, nuclear industry, rocket space engineering, etc.

Hi,

I am working on effects of Blast Loading in sandwich composites using Abaqus. I want to incorporate Cohesive behaviour at the interface of the two materials in the sandwich composite structure i am analysing.
