Zakres tematyczny

Lecture
Concept of loss of stability. Basic stability criteria. Static method, energy method and dynamic method for determining critical load. Critical points: stable bifurcation point, unstable bifurcation point, limit point. Effects of load and geometric imperfections on stability. Flexural stability, torsional stability, flexural stability of bar elements. Dislocation of flexural elements. Compression plate stability and shear plate stability. Stability of shells. Initial stability versus non-linear stability. Consideration of geometrical nonlinearities and physical nonlinearities. Non-conservative problems. Stability versus 2nd order theory. Structural stability in terms of standard regulations: metallic structures, wooden structures, reinforced concrete structures. Use of commercial software for determination of critical loads.

Project .
Analytical solution of the stability problem of a discrete system with one degree of freedom. Application of Timoshenko's energy criterion to the determination of critical loads on compression members (analytical solution with MathCAD support). Application of Timoshenko's energy criterion to the determination of the critical stress of compression plates. Verification of the solution using commercial programs (Robot, Cosmos/M).
