Elasticity:It describes the ability of the material to resist the external force and get back to its original shape or size. A high elasticity predicts whether the material is highly elastic or not.Answer and Explanation: The curve of stress versus strain describes the modulus of elasticity. It...
Define stress, strain, and Young's modulus of an elastic material. Discuss the difference between the modulus of rigidity and the modulus of elasticity with an example. Is the young's modulus of ASTM A992 steel the same as the shear modulus of elasticity? Define the terms s...
基本解释 材料在弹性限度内应力与应变的比值。材料的弹性模量越大,受力时越不易变形。也叫弹性模数。 词语来源 该词语来源于人们的生产生活。 词语简介 [elastic modulus;modulus of elasticity] 物体的应力与相应的应变之比(例如体积弹性模量,切变弹性模量和杨氏模量) 词语造句 1、砌体结构中的一个重要力学参数是弹...
Xylem pressure at 50% conductivity (xylem-P-50), leaf turgor loss point (TLP), cellular osmotic potential (pi(o)), and cellular bulk modulus of elasticity (epsilon), all traits mechanistically linked to drought tolerance, were measured on upper canopy branches and leaves of mature trees from...
Among solids, liquids and gases, which can have all the three modulus of elasticity? The force F acting on a body moving in a circular path depends on mass of the body (m) velocity(v) and radius (r) of the circular path. Obtain the expression for the force by dimensional analysis met...
19, one with class I and the other with class II pMHC, based on Kramer’s kinetic theory and accounted for the 3D coarse-grained structures, molecular elasticity, and conformational changes of the TCR–pMHC-I/II complexes. Previously, several models have been developed to describe catch-slip ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
fly ash are employed in the mix. While excluding coarse aggregates, only silica sand 250 m in grain maximum and 110 m average sizes is used. The PVA fibers are 39 m in diameter, 12 mm in length and have modulus of elasticity of 25.8 GPa. ASTM类型I波特兰水泥和低钙类F飞烟在混合被使用...
When the strength of the weak interlayer bond is below a critical value compared to the strength of the lamina, the nucleated cracks in each lamina are deflected onto the interface followed by interface failure5–7, then it becomes a discontinuously laminated structure. Within the structure, the...
