Symposium on Microelectromechanical Systems: Materials and Devices, MRS Fall 2007
From the Call for Papers:
Microelectromechanical Systems (MEMS) represent the integration of miniaturized mechanical, chemical, fluidic, and optical devices with microelectronics. MEMS have a broad range of applications in optical- and radio-frequency communications, physical/chemical/biosensing, display technology, drug delivery, and the manipulation and isolation of cells.

How to simulate corrosion layer using ABAQUS
Dear Forum Members:
Does anyone have a chance to simulate a corrosion layer using ABAQUS? If yes, could you please explain to me what type of constitutive model you use; i.e. UMAT?
Thank you and best regards,
Homework problems 20-25, Fracture Mechanics
This set is related to buckle-driven delamination, crack bridging, and interfacial cracks.
Modelling of thermomechanical treatment
Dear mechanicians,
I am trying to get the information, orientation on the modelling of thermomechanical treatment of steel (Duplex stainless steel), since during the treatment process, both tensile stress and temperature (150oC-300oC) are applied for a time interval and as a result the original phases of material change to new phases. After the thermomechanical treatment, we get the new materials with different mechanical properties such as elastic limit, yield stress, ductility....
Lectures 14 & 16; Matrix cracking, cracks intersecting an interface, and crack kinking
Matrix cracking in composites and the competition between penetration and deflection when a crack approaches an interface, and the competition between advance in the interface and kinking out of the interface for an interface crack.

Would anyone have spec sheets for the load cell of the LIDO multijoint systemII?
I want to convert the torque readings from volts to newton-meter. I know LIDO dynamometer gives output as torque. But, our lab does not have any spec sheets or manuals, as this system is an old donated system.
