Hi everyone. I am making a model that glass breaks under pressure. Is it correct to define the load in DEFINE_CURVE and LOAD_BODY_Z ㅁas shown in the picture below? I look forward to your reponse. Thanks.

Hello, 

DEFINE_CURVE and LOAD_BODY_Z cards are frequently used to define gravity, thus a value of 0.00981 in the load curve. Is the glass breaking under gravity, or is there another load acting on it? 

Please let me know. 

Thanks,
Alex

I want to apply another load acting on the glass. no gravity. Thanks.

I tried setting it to 10 instead of 0.00981, but the glass didn't break. Could you help me?

Hello, 

To apply loads at the specific node/s the keywords *LOAD_NODE/*LOAD_NODE_SET can be used. Please look at the KW II.
