damage
Alcohol abuse is thought to be a risk factor for the cause of liver damage, hyperlipidemia and insulin resistance.
      
Optimal replacement for discrete additive damage models: Algorithm
      
A system receives shocks at successive random points of discrete time, and each shock causes a positive integer-valued random amount of damage which accumulates on the system one after another.
      
The system is subject to failure and it fails once the total cumulative damage level first exceeds a fixed threshold.
      
There appear many Internet-scale worm incidents in recent years, which have caused severe damage to the society.
      
Chinese pine caterpillar (Dendrolimus tabulaeformis) larvae were fed with pine needles of different degrees of damage to evaluate the effects of pine needles on the growth and development of larvae.
      
Results show that five insect species infect and damage Pinus massoniana, which had been infected by pine wood nematodes, among which four are wood boring beetles and one termite.
      
Also, the damage level considerably influenced the changes of induced volatile products from leaves.
      
The AD and ID leaves at the damage level of 25%-40% did not exhibit an obvious regularity with time; however, in 60%-75% AD leaves, peaks of volatile substances were attained after 1 or 2 h.
      
Nonlinear cumulative damage model for multiaxial fatigue
      
On the basis of the continuum fatigue damage theory, a nonlinear uniaxial fatigue cumulative damage model is first proposed.
      
In order to describe multiaxial fatigue damage characteristics, a nonlinear multiaxial fatigue cumulative damage model is developed based on the critical plane approach.
      
The proposed model can consider the multiaxial fatigue limit, mean hydrostatic pressure and the unseparated characteristic for the damage variables and loading parameters.
      
The recurrence formula of fatigue damage model was derived under multilevel loading, which is used to predict multiaxial fatigue life.
      
The results showed that the proposed nonlinear multiaxial fatigue cumulative damage model is better than Miner's rule.
      
Estimation of fatigue damage of airplane landing gear
      
The computed results show that the landing damage to the fighter and transport airplanes is 75% and 60% of the total damage, and the damage caused by the landing stroke is 40% of the landing-gear damage.
      
The fatigue damage properties can provide important information for reliable designing and the structural optimization.
      
The cavitation erosion damage process of dynamically loaded journal bearings
      
The cavitation damage model was built using finite element analysis software MSC.Marc.
