Eroding plastic strain

WebMay 18, 2024 · However, the enhancement factor of the failure strain is less than that of the strength factor; thus, in this section, a tensile failure strain of 1E-3 is adopted for the concrete as the eroding plastic strain, meaning that a component of the lining fails and is deleted upon reaching this threshold value . WebMar 23, 2012 · Plastic strains yield in the specimen before reaching peak point (maximum strains specimen able to bear before failure). Elastic and plastic zone of specimen depends on the stiffness, brittleness and ductility of specimen. Specimen having higher strength will lead to smaller strains and elastic portion in this case will be more. About The Author
