Abstract

Stresses in the vicinity of the crack tips are responsible for failure of crack-containing components. The singular stress contribution is characterised by the stress intensity factor K, the first regular stress term is represented by the so-called T-stress. Whereas in the main volume, IKM 50, predominantly one-dimensional cracks were considered in homogeneous materials, this supplement volume compiles new results on one-dimensional and two-dimensional cracks.

Abstract

Failure of cracked components is governed by the stresses in the vicinity of the crack tip. The singular stress contribution is characterised by the stress intensity factor K, the first regular stress term is represented by the so-called T-stress. Sufficient information about the stress state is available, if these two parameters are known Results for K and T are compiled in form of figures, tables, and approximate relations.

Abstract

Dear Colleagues,Determinations of the indentation hardness properties of crystals have expanded to cover the full characterizations of their important elastic, plastic and cracking behaviors, particularly as accomplished with the increased measuring capabilities of nanoindentation hardness testing. No crystal structure of any bonding type is either too soft or too hard to prevent measurement with a suitable probing indenter. The current Special Issue is devoted to surveying the topic with emphasis given in a collection of reports to: (1) the diversity of crystals being tested; (2) the variety of measuring techniques; and (3) the wealth of information being obtained.Prof. Dr. Ron ArmstrongDr. Stephen WalleyProf. Dr. Wayne L.

Abstract

In this Special Issue of Metals, an open access forum is provided for publishing original papers that the covers direct and effective correlations between a wide range of thermomechanical processing routes and generated microstructure, hence, the final physical and mechanical properties of the materials. The following aspects of the science and engineering of various metals and alloys are covered in this book:• Original research studies that relate to the understanding of the properties obtained following specific processing/heat treatment route (Experimental, theoretical, and simulation modeling).• Understanding the mechanisms involved in microstructure evolution and phase transformation during processing of materials, specifically as they relate to the understanding of final mechanical properties.• Nano/micro/macro structure characterization and chemistry of metals/alloys used in automotive, power generation, nuclear, aerospace, and medical applications.• Micro/macro texture devolvement during thermo-mechanical processing of metals/alloys.

Abstract

The present work deals with multi-field contact problems in the context of IGA. In particular, a thermomechanical as well as a fracture mechanical system is considered, where novel formulations are introduced for both. The corresponding discrete contact formulations are based on a variationally consistent mortar approach adapted for NURBS discretized and hierarchical refined surfaces. Finally, the capabilities of the proposed framework are demonstrated within numerous numerical examples.

Abstract

Engineering mathematics is a branch of applied mathematics where mathematical methods and techniques are implemented for solving problems related to the engineering and industry. It also represents a multidisciplinary approach where theoretical and practical aspects are deeply merged with the aim at obtaining optimized solutions. In line with that, the present Special Issue, 'Engineering Mathematics in Ship Design', is focused, in particular, with the use of this sort of engineering science in the design of ships and vessels. Articles are welcome when applied science or computation science in ship design represent the core of the discussion.
