I apply force using one slider to another slider. Best part is one slider move little bit and help second slider to slide 6 times length at 70 % force.

Energy Used to move first slider=force*distance

=100N*0.05m

=5Nm

Energy Get on Other Slider= Force*Distance

=Force applied by first slider*cos(45`)*distance

=100*0.7*0.25

=17.5

We get 3 times energy on second slider than we use to move first slider.

A lot work has been done/published in the area of in-situ mechanical testing using electron microscopy. Please list which, according to what you feel has had a significant impact. Here are two in my opinion:

Uchic, M. D., Dimiduk, D. M., Florando, J. N., & Nix, W. D. (2004). Sample dimensions influence strength and crystal plasticity. Science, 305(5686), 986-989.

Salam everyone,

I am working on Modeling of a Brick Wall Panel under reverse cyclic load with a concrete lintel at the top.

i need help regarding displacement controlled test in abaqus. there are a total of 24 cycles . . . first four cycles are force controlled (whose frequency is 1/60Hz) and the rest 20 are displacement control (whose frequency is 1/120Hz) . . . the following is the data file . . .

fault diagnosis

acoustics and vibrations

I am going to finnish my Ph.D. of mechanical engineering with a thesis in the field of vibration assisted fault diagnosis in about 3 months. My main field of research is vibration and I have worked extensively on gear systemes vibration modeling and diagnostics.

Currently I am looking for a postdoc position at which I can continue my researches in the abovesaid fields.

EST method with GNU Octave

research

The EST method -- http://www.e-uni.ee/e-kursused/estmethod/ -- http://digi.lib.ttu.ee/estmethod/ESTmethod.pdf -- is a general computational method, for solving boundary value problems for the structural analysis of frames, beams, and trusses. Differential equations are considered here together with a set of boundary conditions. Compatibility equations for joint displacements and equilibrium equations for member end forces at joints serve as boundary conditions.
