DOI: 10.1007/s10338-019-00110-w
Abstract: Widely distributed in natural deposits, the overconsolidated (OC) clays have attracted extensive experimental investigations on their mechanical behaviors, especially in the 1960s and 1970s. Based on these results, numerous constitutive models have also been established.… read more here.

DOI: 10.1016/j.ijimpeng.2019.103329
Abstract: Abstract Concrete structures are commonly exposed to low velocity impact loads originating from windborne/waterborne debris, vehicle/vessel collision, and rock fall. For the performance assessment of concrete structures under such loads, several constitutive models have been… read more here.
