%X Du-ring ex-plo-i-ta-ti-on of struc-tu-res, sur-fa-ce cracks may de-ve-lop, thus it is be-ing in-ve-sti-ga-ted a new tec-hno-logy which uses na-no-co-a-ting by ma-te-ri-al with na-no-con-ta-i-ners that ha-ve he-a-ling agents for ma-te-ri-al polyme-ri-za-ti-on. Ex-pe-ri-ments for this new na-no-co-a-ting pro-cess are too ex-pen-si-ve and the-ir con-trol has not yet be-en tho-ro-ughly in-ve-sti-ga-ted; hen-ce, com-pu-ter mo-de-ling can play im-por-tant ro-le.In this pa-per, the pro-cess of na-no-co-a-ting is si-mu-la-ted by Dis-si-pa-ti-ve Par-tic-le Dyna-mics (DPD) met-hod. Be-si-des the stan-dard re-pul-si-ve, dis-si-pa-ti-ve and ran-dom for-ces, used in the DPD met-hod, he-re it is in-tro-du-ced the ad-di-ti-o-nal polyme-ri-za-ti-on for-ce bet-we-en two par-tic-les wit-hin na-no-con-ta-i-ner. The ini-ti-al re-sults de-mon-stra-te mo-ti-on of the he-a-ling agent par-tic-les in-to sur-ro-un-ding struc-tu-ral ma-trix and vo-lu-me frac-ti-on di-stri-bu-ti-on in-si-de a small rec-tan-gle crack do-ma-in.
