Geometrical imperfection and adiabatic shear banding

International Journal of Impact Engineering, 2008
Abstract This work addresses the effect of small geometrical imperfections on adiabatic shear band (ASB) formation. The separate effect of the length and radius of short notches is systematically investigated in AM50 and Ti6Al4V alloys, using shear compression specimens.

Dynamic Instability and Resonances of Geometrically Imperfect Plates

Volume 1D: 16th Biennial Conference on Mechanical Vibration and Noise, 1997
Abstract The parametric resonance and other dynamic instabilities of a rectangular plate with initial geometric imperfections acted upon by parametric excitation have been investigated. The temporal equations of motion describing the non-linear behavior of these plates for large oscillations are solved using a direct integration. Results

Dynamic Stability of Shallow Arches with the Geometrical Imperfections

2009 International Joint Conference on Computational Sciences and Optimization, 2009
The dynamic stability of the hinged-hinged sinusoidal shallow arch with geometrical imperfection under time wise distributed load is investigated in this paper. First, the nonlinear governing equation of shallow arch is derived from the d’Alembert principle and Euler-Bernoulli assumption.

Stability of Geometrically Imperfect General-View Shells

International Applied Mechanics, 2000
The authors discuss a numerical algorithm which allows to study the loading curves in order to find out the singular points which are the boundary and bifurcation points. As example the stability of a finite panel is studied with allowance for the form imperfection.
