Damage control surgery: a constant evolution
Colombia Medica, 2020 The story of trauma resuscitation is similar to that of many other advances in medicine: described, forgotten, reinvented, ridiculed, and finally accepted. Even after acceptance, the concepts go through periods of neglect and indifference before they are tried and enhanced, till the next advance.

Effect of Fracture Coincidence on Mechanical Properties and Damage Evolution of Sandstone
Meikuang Anquan, 2020 To study the effect of fracture coincidence on mechanical properties and damage evolution of fractured sandstone, five kinds of sandstone specimens with different crack distributions were simulated by RFPA2D software under uniaxial compression test. The

Damage-cluster distributions and size effect on strength in compressive failure [PDF]
, 2012 We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local damage and reproduces the main features of compressive failure of brittle ...
