Numerical modelling response of laser welded sandwich panel under three-point bending test

The sandwich structure is known by inner and outer faces which acted compositely with relatively low strength core. Sandwich panel consisted of two thin and stiff skins and separated by a thick and lightweight core. The objective of this study to predict the behaviour of the laser-welded sandwich panel under three-point bending test. Numerical modelling of laser-welded was studied and run under bending loading. The sandwich panels were studied...
