<p> <\/p><p>Hello,<\/p><p>Peridynamics in LS-DYNA has been used before to model crack propagation in concrete. But, note that the peridynamics method in LS-DYNA is limited to only 2 material models:<\/p><p>*MAT_ELASTIC_PERI<\/p><p>*MAT_ELASTIC_PERI_LAMINATE<\/p><p>And these material models do not have temperature dependence. If the temperature of your concrete part is constant, then you could calibrate the model for this particular temperature.<\/p><p>If you Google “LS-DYNA cmmg peridynamics”, you will find information from the lstc-cmmg website and more links.<\/p><p>Note that you can click in the letters or number in between brackets in the lstc-cmmg website to access more information and example models.<\/p><p><\/p><p> <\/p><p><span class=””ui-provider” dir=””ltr””>Even though there is no temperature dependence in the peridynamics material models, we can now model thermal expansion. You can define a zone with different temperatures using *DEFINE_FUNCTION and then include it in *MAT_ELASTIC_PERI:<\/span><\/p><p><span class=””ui-provider” dir=””ltr””> <\/a>\"\"<\/span><\/p><p><span class=””ui-provider” dir=””ltr””> <\/a>\"\"<\/span><\/p><p>The gf parameter in *MAT_ELASTIC_PERI refers to the *DEFINE_FUNCTION ID and the alpha parameter is the thermal expansion coefficient.<\/p><p> <\/p><p>Let me know how it goes.<\/p><p> <\/p><p>Reno.<\/p><p> <\/p><\/p>\n","protected":false},"template":"","class_list":["post-320140","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
