It is with great pleasure that I present to the public the masterful treatise of Professor L.M. Kachanov on delamination buckling of composite materials. As the author has pointed out so rightly, an application of composite materials becomes more and more common in many branches of engineering practice. Therefore, it is essential that designers are aware of possible failure modes of such materials and understand their mechanisms. One of these failure modes is delamination buckling, and Professor L.M. Kachanov presents its theory in this book in his usual ingenious way.H. Leipholz
