Editing Magnetorheological fluid (section)

=== Shear strength ===

Low [[shear strength]] has been the primary reason for limited range of applications. In the absence of external pressure the maximum shear strength is about 100 kPa. If the fluid is compressed in the magnetic field direction and the compressive stress is 2 MPa, the shear strength is raised to 1100 kPa.<ref>{{cite book |last1=Wang |first1=Hong-yun |last2=Zheng |first2=Hui-qiang |last3=Li |first3=Yong-xian |last4=Lu |first4=Shuang |chapter=Mechanical properties of magnetorheological fluids under squeeze-shear mode |editor-first1=Yetai |editor-first2=Kuang-Chao |editor-first3=Rongsheng |editor-last1=Fei |editor-last2=Fan |editor-last3=Lu |title=Fourth International Symposium on Precision Mechanical Measurements |date=17 December 2008 |volume=7130 |pages=71302M |doi=10.1117/12.819634 |chapter-url=https://ui.adsabs.harvard.edu/abs/2008SPIE.7130E..2MW/abstract |bibcode=2008SPIE.7130E..2MW|s2cid=137422177 }}</ref> If the standard magnetic particles are replaced with elongated magnetic particles, the shear strength is also improved.<ref>{{cite journal |last1=Vereda |first1=Fernando |last2=de Vicente |first2=Juan |last3=Hidalgo-Álvarez |first3=Roque |title=Physical Properties of Elongated Magnetic Particles: Magnetization and Friction Coefficient Anisotropies |journal=ChemPhysChem |date=2 June 2009 |volume=10 |issue=8 |pages=1165–1179 |doi=10.1002/cphc.200900091 |pmid=19434654 |url=https://archive.today/20130105064549/http://www3.interscience.wiley.com/journal/122380920/abstract|url-access=subscription }}</ref>
