Modelling,　Solving　and　Applications　for　Topology　Optimization　of　Continuum　Structures:　ICM　Method　Based　on　Step　Function　provides　an　introduction　to　the　history　of　structural　optimization,　along　with　a　summary　of　the　existing　state-of-the-art　research　on　topology　optimization　of　continuum　structures.　It　systematically　introduces　basic　concepts　and　principles　of　ICM　method,　also　including　modeling　and　solutions　to　complex　engineering　problems　with　different　constraints　and　boundary　conditions.　The　book　features　many　numerical　examples　that　are　solved　by　the　ICM　method,　helping　researchers　and　engineers　solve　their　own　problems　on　topology　optimization.　This　valuable　reference　is　ideal　for　researchers　in　structural　optimization　design,　teachers　and　students　in　colleges　and　universities　working,　and　majoring　in,　related　engineering　fields,　and　structural　engineers.　©　2018　Tsinghua　University　Press　Limited.　Published　by　Elsevier　Inc.　All　rights　reserved.
