Study of the simple extension tear test sample for rubber with Configurational Mechanics

Submitted by ErwanVerron on
research

The simple extension tear test-piece also referred to as the trousers sample is widely used to study crack propagation in rubber. The corresponding energy release rate, called tearing energy for rubber materials, was first established by Rivlin and Thomas (Rupture of rubber. I. Characteristic energy for tearing. J. Polym. Sci., 10:291–318, 1953); a second derivation was proposed later by Eshelby (The calculation of energy release rates. In G. C. Sih, H. C. van Elst, and D. Broek, editors, Prospects of Fracture Mechanics, 69–84, Leyden, Noordhoff, 1975).

Bi-functional optimization of actively cooled, pressurized hollow sandwich cylinders with prismatic cores

multifunctional material

All metallic, hollow sandwich cylinders having ultralight two-dimensional prismatic cores are optimally designed for maximum thermo-mechanical performance at minimum mass. The heated cylinder is subjected to uniform internal pressure and actively cooled by forced air convection. The use of two different core topologies is exploited: square- and triangular-celled cores. The minimum mass design model is so defined that three failure modes are prevented: facesheet yielding, core member yielding, and core member buckling.

Submitted by qiuyifa on

Dear Friends.

    I want to simulte the mechanic behavior of of Fiber Reinforced Composites and Textile Reinforced Composites.

    Could you give me some advice on which software is suitable?

Thank you in advance

proposal

In response to a NSF call for proposal on Cyberinfrastructure Training, Education, Advancement, and Mentoring for Our 21st Century Workforce (CI-TEAM), in June 2006, several of us submitted a proposal entitled "iMechanica:  Leveraging Cyberinfrastructure to Evolve All Knowledge of Applied Mechanics"

I'd like to know something about Carbon Fiber

Submitted by aitang on

Dear all,

 Recently I got something info from my colleagues about Carbon Fiber. Now more and more this kind material is using in Aerospace, and it has a very nice future.

As it's very abrasive when cutting it, so there's lots of problems for machining.

So, could you anyone give me some info about this material? or where can I go for it?

 thanks a lot
