Special Issue "Mechanics of Biomaterials"

Submitted by azadpoor on
The mechanical behavior of biomedical materials and biological tissues are important for their proper function. This holds true, not only for biomaterials and tissues whose main function is structural such as skeletal tissues and their synthetic substitutes, but also for other tissues and biomaterials. Moreover, there is an intimate relationship between mechanics and biology at different spatial and temporal scales. It is therefore important to study the mechanical behavior of both synthetic and living biomaterials.

how to model a CFRP sheet attached to concrete using resin by ABAQUS

Submitted by wael_alawsey on
software

hello everybody ..

iam trying to model a one-way rc slab with opening and strength that opening using CFRP sheets by attaching it to the concrete slab using resin as a cohesive layer 

i have the properties of CFRP sheet ( thickness,tensile strength,elastic modulus,ultimate tensile strength)

also have the resin ( epoxy) properties (tensile strength,elastic modulus)

so please i need help on how to model all this strengthening using ABAQUS 6.13 

if anyone done that before or have any info about it please update me

regards . . .

PhD Studentship in Design of Polymeric Foams

Submitted by Helen Gardner on

A 4 year project, in collaboration with SABIC, on the design of polymeric foams will be performed at the Cambridge University department of Engineering. The project will explore the relationship between microstructure and macroscopic properties of a range of new reinforced foams, including composite-reinforced foams.

 

Extinct Kangaroos Couldn't Hop

Another couple of interesting articles to share. Using some "mechanics" principles, researchers have reasoned that 100,000 years ago, kangaroos were too heavy to hop.

A while ago, a different group of researchers published the results of computer modelling (using genetic algorithms) that showed dinosaurs might have hopped and skipped as forms of locomotion! (But only if particularly happy?)

These articles might be good to share with undergraduate engineers for discussion in tutorials. There are issues to discuss with assumptions in both cases.

Aerospace engineering

The Department of Aerospace Engineering Sciences in the College of Engineering and Applied Science at the University of Colorado Boulder invites applications for three tenure-track faculty positions in the areas of structures and materials, small satellites, and bioastronautics. Applicants in structures and materials are especially sought with the following research interests: Design, modeling, fabrication, and characterization of structural and/or multi-functional materials and their integration into innovative aerospace systems; preference given to applicants with an experimental focus.
