Recently,I made a model of two parts

1. a circle pad (deformed)

2.a discrete rigid line (move upwords)

the problem is I want to get the reaction force in the rigid surface,but I can not.

 I must get it from the pad because I must make the rigid part more well meshed,I want to get better data.

Could you tell me how to get data in rigid part when contact occur?

Thanks a lot.

The advance of mechanics towards the frontiers of biology and soft matter necessitates an understanding of entropic forces which manifest themselves as thermal fluctuations at length scales of a micron and below. The effects of these fluctuations can be easily seen in biofilaments at thermodynamic equilibrium under the action of forces and moments as they fluctuate around their minimum energy configuration due to Brownian motion. This remains true of filaments in networks and gels such as those of actin, spectrin, fibrin or other biopolymers.

 Hi,

 I wish to calculate an equivalent transverse shear stiffness of a simple sandwich plate. The plate is made of two skins and a layer of a foam.

Does anyone know an analytical formula for determination of equivalent (kGS) ?

 Thank's.
