Hello Everyone,
I try to plot the butterfly curve for piezoelectric material (strain vs. electric field for different applied stress values). Butterfly curve shows the nonlinear response of the piezoelectric material which is a hysteretic response.
I just want to ask you guys if anybody knows a good way to plot butterfly curve for 1-3 piezoelectric materials in matlab????
The TMS Young Professionals Committee is organizing a "Meet the Candidate Poster Session" in conjunction with the general poster session of TMS 2015. This event is designed to create networking opportunities for young professionals and hopefully help them discover prospects for future employment.
The Meet the Candidate Poster Session will provide the opportunity for
As advanced energy materials with higher conversion efficiencies, enhanced storage capacities, and better reliabilities are being developed to meet the ever-increasing global energy needs, mechanics has emerged as one of the key factors that affect the performance of energy systems. In thermoelectric energy conversion for waste heat recovery, thermal stress is a big concern for reliabilities, and the efficiency and reliability of photovoltaic materials is similarly affected by strain and mechanical defects.
Veryst Engineering is offering a 2-day in-person training course on Advanced Structural Mechanics using COMSOL Multiphysics. The course will be in Houston on November 3-4, and it will cover basic and advanced structural/solid mechanics capabilities in COMSOL including contact, material modeling, and fatigue. I will teach the course together with Dr. Stuart Brown, Veryst’s Managing Principal.

POSTDOCTORAL ASSOCIATE POSITION University of Pittsburgh The Shankar Research Group (www.shankarlab.pitt.edu) at the University of Pittsburgh anticipates an opening for a postdoctoral associate starting tentatively in September 2014. The position’s primary area of research will focus on mechanical instabilities and actuation in structures fabricated from photoresponsive, azobenzene-functionalized liquid crystal polymers and polyimides. A background in experimental mechanics and mechanical characterization is required.

The reproducing kernel element method is a numerical technique that combines finite element and meshless methods to construct shape functions of arbitrary order and continuity, yet retains the Kronecker-δ property. Central to constructing these shape functions is the construction of global partition polynomials on an element. This paper shows that asymmetric interpolations may arise due to such things as changes in the local to global node numbering and that may adversely affect the interpolation capability of the method.
