1-3 Piezoelectric Butterfly Curve

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????

Mechanics of Materials Special Issue on Mechanics of Energy Conversion and Storage

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.

COMSOL Course in Houston - Advanced Structural Mechanics

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.

Symmetric global partition polynomials for reproducing kernel elements

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.

Post-doctoral position at McGill/Polytechnique Montreal on crystal plasticity

I have a 2-year post-doctoral position available at McGill/Polytechnique to work on the effect of shot peening on the residual stresses at the grain levels. The methodology will consist of meshing representative volume elements of polycristals and submitt them to shot peening (explicit dynamic simulations). I require a candidate who has exprience in FE modeling of Representative Volume Elements of polycristals and crystal plasticity.

von-mises stresses in solid model with and without pores

Hello Everyone,

My name is Muhammad Imran and I am a PhD student in TU, Dortmund. I am performing tensile test simulation in Abaqus for aluminium silicon alloy. I am calculating stresses for three different models, one model is solid (zero porosity) and second model has a cavity inside and third model has some pores inside.
