### Synopses & Reviews

This work treats structural and continuum mechanics in a unified and consistent manner.Analytical and graphical methods are given equal emphasis to account for the contemporary requirements of computer applications on one hand, and visualization and insight on the other hand. Therefore, all theoretical developments are presented both in the text and by means of an extensive set of figures. Text and figures complement each other, and this twofold presentation is also used in the examples. In the same spirit, both formal and intuitive (engineering) arguments are used in parallel to derive the principles used for instance in Bending Moment diagrams and Shear Stress diagrams. Importantly, sign conventions for member forces are related to the stress definitions of continuum mechanics and then applied consistently throughout the series.

#### Review

From the reviews: "This is the second of two volumes ... by Hartsuijker and Welleman (both, Dolft Univ. of Technology). ... The concepts and applications are well presented; applications include both basic and advanced levels. The worked out examples nicely illustrate concepts. Figures and tables are clear and help understanding of the concepts. ... In summary, the book is very well written and is a welcome addition to the literature of engineering mechanics. Summing Up: Recommended. Lower-division undergraduates through professionals." (M. G. Prasad, CHOICE, Vol. 45 (7), 2008)

#### Synopsis

This work treats structural and continuum mechanics in a unified and consistent manner.
All theoretical developments are presented both in the text and by means of an extensive set of figures. Text and figures complement each other, and this twofold presentation is also used in the examples. Volume 2 covers stresses and strains in simple elements subjected to extension, bending, shear and torsion. For elementary structures like trusses, beams and frames, displacements due to simple loads are obtained using both classical mathematical descriptions with differential equations and engineering methods like Williot diagrams for (simple) trusses and "forget-me-nots" and moment-area formulae for bending.

#### Synopsis

Here is a systematic and clearly laid out text on structural and continuum mechanics. Containing hundreds of diagrams, drawings and examples, this work dovetails theoretical developments and figures in a beautifully conceived treatment of the subject. The book also covers stresses and strains in simple elements subjected to extension, bending, shear and torsion. For elementary structures, simple load displacements are obtained using both classical mathematics descriptions and engineering methods like Williot diagrams.
