Abstract
The response of circular GLARE fiber-metal laminates subjected to low velocity impact by a hemispherical impactor is treated analytically. Using a quasi-static approach, characteristic impact variables are calculated. A force-deflection relation is determined and employed for the unloading impact stage. Delamination is also considered. Application to GLARE 4-3/2 and GLARE 5-2/1 plates is implemented. The predicted maximum impact load, its application time, and the total impact duration agree well with published experiments. The derived formulas can be used to evaluate impact response of GLARE or other similar hybrid laminates. No other solution of this problem is known to the authors.
