Is anyone familiar with deriving shape functions for different beam end conditions?

I am doing my research in nonlinear vibration of beams. In that research, I have to derive the shape function for different end conditions of the beam. Regarding this,I need some ideas. Are there books I can reference?

Thank you for your help.

I would like to use condensation to calculate the normal modes of
a structure. These grids are connected to the structure through RBE3 (master
grid). Let me know if there's a way to use the master grids of RBE3 elements in
the A-SET?

I heard a sound in my email Inbox. It was from the editor-in-chief of Elsevier's Engineering Failure Analysis journal. I opened the email and read that my paper was accepted to be published under some conditions for revisions per peer reviewer's comments.

damage/failure of composite materials

I am new in using abaqus, please can any one help me with tutorials, book or anything that guide me on how to simulate failure and damage progressive in composite materials using abaqus.

Thanks you all

Greetings,

I'm conducting a simple shear test (single lap joint) between aluminum bonded with 3M adhesive. 
Adhesive material is 3M VHB 4930 adhesive (acrylic)

Result obtains = 
Load vs Displacement Curve
True Stress vs Stretch Ratio

From the literature, mostly they used Yeoh model for 3M adhesive (Modeling and simulation of dielectric elastomer actuators,M.Wissler 2005).
