Correct "out-of-range forces" problem with *CONTACT_AUTOMATIC_..._TIEBREAK, OPTIONs 7 and 10. Only affects MPP. Fix MPP *CONTACT_TIED_SHELL_EDGE_TO_SURFACE_BEAM_OFFSET: solids were in some cases still unstable, particularly if the user specified a large contact thickness (positive or negati...
Fix for OPTION=7 of *CONTACT_AUTOMATIC_..._TIEBREAK. The failure equation adopted from the paper of Lemmen and Meijer was wrong. This is now corrected in the code and in the manual.Correct "out-of-range forces" problem with *CONTACT_AUTOMATIC_..._TIEBREAK, OPTIONs 7 and 10. Only MPP...

LS-DYNA Damping阻尼设置 LS-DYNA Damping 在LS-DYNA中阻尼完全是可选的,通过使用一个*DAMPING卡片来调用。应该知道能量可以通过其它的非*DAMPING的方式耗散,比如,因为沙漏力产生的能量,刚性墙的力产生的能量,接触摩擦力产生的能量,离散阻尼产生的内能等。有时候,接触力可能将噪声引入到响应里。在这种情况下,...
Added an error if *INITIAL_VELOCITY_GENERATION_START_TIME STIME is out-of- range of the analysis termination time. • Case 47360 Autofix in high order solids was getting confused with interpolation nodes that are either in the wrong order, or simply slightly moved from their theoretical ...
11.Other forces that the dynamometer exerts on the vehicle are set out in SAE standards J2263 and J2264. 12.By the time the 10-mile (16-km) Highway Fuel Economy Test was added in 1974, the tests were performed in a lab on a dynamometer. ...
The EM module allows the introduction of a source of electrical current into solid conductors and the computation of the associated magnetic field, electric field, as well as induced currents. The EM solver is coupled with the structural mechanics solver (the Lorentz forces are added to the ...
Out-of-range forces were likely to occur. *MAT_181: AVGOPT<0 means that |AVGOPT| is a time interval over which strain rates are averaged. *MAT_106: Plasticity algorithm is made more robust. *MAT_034: Fix paradoxical behavior in transverse shear for bending option (ECOAT,SCOAT,TCOAT)...
Fix out-of-range forces after dynamic relaxation when using VP=1 for *MAT_PIECEWISE_LINEAR_PLASTICITY and non-zero strain rate parameters, C & P, and the part goes into plastic deformation during dynamic relaxation. Fixed unit transformation for GAMAB1 and GAMAB2 on *MAT_DRY_FABRIC. We were...
