Abstract--L-shaped beams subjected to pure elastic-plastic bending are investigated thoroughly. The shifting and rotating of the neutral axis of the beam during bending and springback after unloading are described mathematically, while the curvatures of the beam before and after springback are given. The method proposed in this paper is valuable both to the further theoretical studies of the as...

A package characterization technique using coplanar waveguide (CPW) probes and line–reflect–match (LRM) calibrations for surface-mountable packages is presented. CPWto-package adapters (CPA) are fabricated on alumina substrates to mount and measure the high-frequency response of plastic packages. Offset CPA standards in conjunction with an LRM calibration are used to de-embed the response of th...

Amorphous silicon (a-Si) thin film transistors (TFT’s) were fabricated on free-standing, clear plastic substrates with a maximum process temperature of up to 250°C. An a-Si TFT backplane for active matrix OLED (AMOLED) application was also made on such substrates. The performance of both the TFT’s and the AMOLED backplane are excellent. These results will enable the fabrication of flexible AMLC...

an evolutionary structural optimization (eso) method is used for plastic design of frames. based on safe theorems some criteria are derived and made an effort to satisfy them during the optimization process. in this regard, equilibrium is checked and yield condition is gradually satisfied during the optimization process. in this method, the amount of used material and the stiffness for each ele...

mechanical stress and maximum superconducting current have been calculated for a superconductor subjected to uniform plastic deformation. The training effect due to strain hardening o f the material is discussed. These results are compared with an analogous case when the normal transition is caused by the thermo-magnetomechanical instability. The quenching current is shown to depend on the hist...

The current paper primarily aims to suggest a mathematical model for the shape-dependent term of Khan- Liu (KL) Yield/ fracture criterion as a function of Plastic Strain for DP590 steel alloy. The shape-dependent term in the mention criterion can generalize the application of this criterion in order to predict the behavior of other materials. Plane stress case and the first quarter of the stres...
