Prediction of Buckling-Induced Delamination Growth Onset in Composite Laminates

A one-dimensional analytical solution to predict buckling-induced delamination growth was developed toward an efficient and effective engineering application. The postbuckling solution for a composite beam was first obtained with nonlinear deflection approximations based on 'thin film' assumption. An interlaminar stress analysis method was then...

Numerical Simulations of Spirally Welded Steel Tubes Under 4-Point Bending

This master thesis investigates the response of spirally welded steel tubes under 4-point bending deformation. Through the finite element simulations of a testing the buckling behavior of sprirally welded tubes can be more clearly understood. The numerical simulation and buckling behavior of spirally welded steel tubes is discussed in this...
