Analysis of response to the external compressive force on tomatoes;

The sdy about mechanical model and the analysis of response to the external compressive force about grape;

With the aid of the Muskhelishvili s complex potentials theory, boundary conditions on the crack faces and the single value condition of displacement, the problem of a plate under compressive loading is turned into Hilbert problem and the fundamental solution for cracks with different surface forms under concentrated pseudo-tractions are given.

Mechanical model of grape under compression load;

Based on Koiter s upper bound shakedown theorem, the cynulation of plastic deformation in cylindrical thin shells subjected to cyclically moving thermal load and stationary mechanical loads is analyticaly discussed.

Nonlinear bending and stability of beams subjected to mechanical and thermal loads;
