2nd spatial derivatives from isoparameteric elements

Based on my limited knowledge of FEM, I find it is difficult to use isoparametric elements for any problem whose governing
functional involve the second (or higher) partial derivatives of the unknown
functions. I hope some computational mechanicians can help me on this. Currently, I have a formulation derived from micropolar elasticity which has a functional involving second partial derivatives of the displacements. Thanks a lot for any of your suggestions.
Material model for high cycle fatigue
In fatigue analysis, it is common to use S-N curve from database for spesific material, and some time for spesific way of loading. Is there any way to predict fatigue from direct simulation? For example, giving cyclic loading (10^5 times) and the material will suffer damage and eventually failed. In some FEM codes (MARC, LSDYNA, etc) there is Lemaitre-Chaboche model used to analyze material behavior under low cycle cyclic loading.
Thanks in advance

Design Centered Mechanical Engineering Graduate Programs?
I would like to pursue graduate study in thefield of mechanical engineering design. I am familiar with Stanford's JointProgram in Design which emphasizes Human-Centered Design, Design Creativity,and Desirability along with standard graduate engineering subject matter. Ihave not however been able to locate other graduate schools which emphasizedesign methodology in such a way. I would be very interested if anyone hasknowledge of schools who teach similar design centered graduate programs.
