内容简介

This book summarizes several latest works about lattice structure topology optimizationincorporated with additive manufacturing constraints， aiming to find a balance between result optimalityand computational efficiency， while simultaneously dealing with the heterogeneity connectivity andmanufacturability for additive manufacturing. The first chapter introduces the fundamentals of topologyoptimization and its latest development trend. Then， Chapter 2 and 3 present the parametric latticestructure optimization methods incorporating both solid and void phases. Chapter 4 extends the methodthrough clustering to support freeform multiscale topology optimization that ensures inter-connectivity. Then， in Chapter 5 and 6， the critical issues of 3D printing the organic structures through ceramic vatphotopolymerization and continuous fiber composite material extrusion are addressed by addingconstraints. The strength design issues related to lattice structures are resolved in Chapter 7. The abovecontents reflect the frontiers of lattice structure topology optimization， and MATLAB codes are attachedat the end of the chapters. This book would be beneficial for junior researchers doing research aboutdesign and manufacture， and it can also be used as a textbook for undergraduate and graduate-levelcourses covering the topics of structural optimization， finite element analysis， and MATLAB coding， etc.
