Q1:Dab tsi ua rau qaug zog ua kom tawg hauv lub kaum sab xis sib txuas?
A1:Cyclic loading (e.g., machinery vibrations) initiates micro-cracks at stress-concentration points like bolt holes or weld toes. Poor surface finish accelerates crack propagation. Undetected slag inclusions weaken the material. Regular dye penetrant inspections identify early-stage tawg . retrofitting nrog cov phaj tuab lossis cov phiaj loj gitigates txuas ntxiv kev puas tsuaj {9}
Q2:Vim li cas thiaj ua kaum sab xis steel txhua thawb nyob rau hauv compressive loads?

Q4:Dab tsi swb tshwm sim los ntawm kev siv vuam tsis raug cai ntawm lub kaum steel?
A4:Tsis ua tiav kev nkag siab tsim cov pob qij txha tsis muaj zog los ntawm kev sib tsoo ntawm hydrogen los ntawm hydrogen kev nyuaj siab {{}}}} kev sim ultrasonic kuaj cov kev sib nraus subsurace txawv ua ntej kev puas tsuaj .
Q5:Yuav ua li cas yog overver tsis tau kuaj pom nyob rau hauv lub kaum sab xis nqaj?
A5:Permanent deformation (e.g., visible bending) indicates overloading. Fractography reveals ductile dimples or brittle cleavage patterns. Comparing actual loads to design calculations confirms exceedance. Strengthening methods include adding steel plates or carbon fiber qhwv . hack mus kuaj nrog quav gauges siv tau kho tau kho tau kho puas cov kev kho tau kho kom haum thiab}}
