ABSTRACT
Du­ring ex­plo­i­ta­ti­on of struc­tu­res, sur­fa­ce cracks may de­ve­lop, thus it is be­ing in­ve­sti­ga­ted a new tec­hno­logy which uses na­no­co­a­ting by ma­te­ri­al with na­no­con­ta­i­ners that ha­ve he­a­ling agents for ma­te­ri­al polyme­ri­za­ti­on. Ex­pe­ri­ments for this new na­no­co­a­ting pro­cess are too ex­pen­si­ve and the­ir con­trol has not yet be­en tho­ro­ughly in­ve­sti­ga­ted; hen­ce, com­pu­ter mo­de­ling can play im­por­tant ro­le.In this pa­per, the pro­cess of na­no­co­a­ting is si­mu­la­ted by Dis­si­pa­ti­ve Par­tic­le Dyna­mics (DPD) met­hod. Be­si­des the stan­dard re­pul­si­ve, dis­si­pa­ti­ve and ran­dom for­ces, used in the DPD met­hod, he­re it is in­tro­du­ced the ad­di­ti­o­nal polyme­ri­za­ti­on for­ce bet­we­en two par­tic­les wit­hin na­no­con­ta­i­ner. The ini­ti­al re­sults de­mon­stra­te mo­ti­on of the he­a­ling agent par­tic­les in­to sur­ro­un­ding struc­tu­ral ma­trix and vo­lu­me frac­ti­on di­stri­bu­ti­on in­si­de a small rec­tan­gle crack do­ma­in.
