Fatigue of composites-fatigue modulus concept and life prediction
Woonbong Hwang,K.S. Han +1 more
TL;DR: In this paper, a new concept called fatigue modulus, defined as a slope of applied stress and resultant strain at a specific cycle is introduced, which is used to predict the fatigue life of glass fiber reinforced epoxy composite materials better than S-N curve or Basquin's relation.
Journal ArticleDOI
Cumulative Damage Models and Multi-Stress Fatigue Life Prediction:
Woonbong Hwang,K.S. Han +1 more
TL;DR: In this paper, three different cumulative damage models were defined using several physical variables such as fatigue modulus and resultant strain, and the proposed models were derived as functions of nor malized applied stress level, r, and number of fatigue cycle, n.
Journal ArticleDOI
3D Cell Printing of Functional Skeletal Muscle Constructs Using Skeletal Muscle-Derived Bioink
Yeong-Jin Choi,Taek Gyoung Kim,Jonghyeon Jeong,Hee-Gyeong Yi,Ji Won Park,Woonbong Hwang,Dong-Woo Cho +6 more
TL;DR: 3D cell‐printing of decellularized skeletal muscle extracellular matrix (mdECM)‐based bioink facilitates the fabrication of functional skeletal muscle constructs and hold great promise for producing clinically relevant engineered muscle for the treatment of muscular injuries.
Journal ArticleDOI
Stacking sequence design of composite laminates for maximum strength using genetic algorithms
TL;DR: In this paper, the authors used GA for the optimal design of symmetric composite laminates subject to various loading and boundary conditions, and the results showed that GA can find the global optimal solution leading to a substantial decrease in the failure index.
Journal ArticleDOI
Triboelectric nanogenerator for harvesting pendulum oscillation energy
Sangmin Lee,Yean Lee,Dongseob Kim,Ya Yang,Long Lin,Zong-Hong Lin,Woonbong Hwang,Zhong Lin Wang,Zhong Lin Wang +8 more
TL;DR: In this article, a pendulum motion based triboelectric nanogenerator (TENG) was developed to sustain its motion with low maintenance providing multiple output peaks from a tiny scale single mechanical triggering.
