What is difference of testing method?
Well...What is their advantages and disadvantages among tensile test, compressive test and torsion test?
plz describe extensively..

The story behind the proof of Fermat's Last Theorem
When I came to the institute, my collaborator Kay invited me for a dinner in the new town together with his friend Thilo and other guys. The city is wisely divided into two functioning areas, old town and new town. All the ancient buildings like King’s summer palace, women’s church and opera house are in the old town; while the restaurants, bars and other modern buildings are in the new town. Each is in harmony with its environment and cultural atmosphere.
Four more Problems of Internal Loading. Having problem determining Internal Loading.
Four more problems of Internal loading. I am having some difficulties solving these problems. Plz someone try these problems and give me a solution.

Multiaxial behavior of nanoporous single crystal copper: a molecular dynamics study
The stress-strain behavior and incipient yield surface of nanoporous single crystal copper are studied by the molecular dynamics (MD) method. The problem is modeled by a periodic unit cell subject to multi-axial loading. The loading induced defect evolution is explored. The incipient yield surfaces are found to be tension-compression asymmetric. For given void volume fraction, apparent size effects in the yield surface are predicted: the smaller behaves stronger.
Stress and Strain: Basic Concepts of Continuum Mechanics for Geologists
This book begins by describing real life examples of mechanical states of different materials. The book next discusses stress. This discussion includes force, mohr circles, tensor components of stress, and stress fields. Next strain is discussed. This ranges from measuring deformation to tensor components of infinite and finite strain. The book concludes by outlining different material behaviors. These include Hookean behavior and Newtonian behavior. This last section also discusses energy consumed in deformation.
I wrote a batch file for Crack growth model for ANSYS but when the soution is running,ANSYS terminate itself...Why?
Hello everybody,
I am searching precision of crack propogation in a bonded wafer double.I wrote a code but the problem is that when I want to solve it in ANSYS, the program is shutdown. I need help about it. Thanks for your helps...
Greetings
Volkan DALMISLI
P.S:The code is given below.
